BACKGROUND: Children struggle to fall asleep by themselves because of their physiological characteristics. Therefore, research has been carried on various devices (such as a smartphone) to assist in improving the sleep quality of children. However, all such devices need to be controlled by parents and do not have functions for monitoring the sleep environment. OBJECTIVE: In this paper, a smart sleep-lighting system that includes a sleep-lighting device and a smartphone dongle is developed to improve the sleep environment of children. METHODS: The temperature, humidity, and luminance of the sleep environment are monitored and analyzed by the sleeplighting device to control multi-color light and audio components. The colored light emitted by the multi-color light can be adjusted to improve the sleep atmosphere. Also, the audio component can play white noise to induce sleep. In addition, parents can use a smartphone dongle with a multi-channel wireless communication method to monitor and control one or more lighting devices in different locations in real time. RESULTS: For environmental monitoring, average difference between proposed device and commercial sensor from chamber setting temperature 15 degrees C to 35 degrees C was 0.588 degrees C +/- 0.10 degrees C, and average error value of the humidity measurement was 0.74% at 40% similar to 60% RH. Also, the manufactured sleep-lighting device shows good performance in multi-color light emission, and playing of white noise. As result, the smartphone connected to the proposed smartphone dongle enables monitoring and control of the proposed lighting device in a wireless well. CONCLUSIONS: The manufactured sleep-lighting device has a high-precision temperature and humidity sensor and a luminance sensor that can accurately monitor the sleeping environment. The lighting device can play white noise to induce sleep in children. Also, a multi-color LED light is operated via a smartphone application to improve the sleep atmosphe

Due to the commercial move and gaming industries, Augmented Reality (AR) technology has matured. By definition of AR, both artificial and real humans can be simultaneously present and realistically interact among one another. With the help of physics and physiology, we can build in the AR tool together with real human day-night webcam inputs through a simple interaction of heat transfer -getting hot, action and reaction -walking or falling, as well as the physiology -sweating due to activity. Knowing the person age, weight and 3D coordinates of joints in the body, we deduce the force, the torque, and the energy expenditure during real human movements and apply to an AR human model. We wish to support the physics-physiology AR version, PPAR, as a BMW surveillance tool for senior home alone (SHA). The functionality is to record senior walking and hand movements inside a home environment. Besides the fringe benefit of enabling more visits from grand children through AR video games, the PP-AR surveillance tool may serve as a means to screen patients in the home for potential falls at points around in house. Moreover, we anticipate PP-AR may help analyze the behavior history of SHA, e. g. enhancing the smartphone SHA Ubiquitous Care Program, by discovering early symptoms of candidate Alzheimer-like midnight excursions, or Parkinson-like trembling motion for when performing challenging muscular joint movements. Using a set of coordinates corresponding to a set of 3D positions representing human joint locations, we compute the Kinetic Energy (KE) generated by each body segment over time. The Work is then calculated, and converted into calories. Using common graphics rendering pipelines, one could invoke AR technology to provide more information about patients to caretakers. Alerts to caretakers can be prompted by a patient's departure from their personal baseline, and the patient's time ordered joint information can be loaded to a graphics viewer allowing for high-definiti

Some reports show that the physiological information measured in hospital is not enough without the one measured in home. The physiological information monitored in home, therefore, is strongly required recently. The goal of this research is to develop a wearable and tractable sensor system for detecting biomedical signals such as cardiac rhythm, respiration, body movement, and percentage of body fat (%BF) and for home health care. A belt type sensor for this purpose is developed, which consists of sensing materials of PVDF film and conductive fabrics. Also several data processing techniques, such as the discrete wavelet transform, cross correlation and adaptive filtering method, were introduced to eliminate noises and base wandering and to extract the specified components. The ECG and respiration signals obtained by the proposed belt type sensor system gave good agreements with commercial medical system. Furthermore, the body fat (%BF) measurement based on the four-electrode BIA was also built in the belt sensor. The body fat was calculated by measuring the body impedance from the belt type sensor and compared with the predicted %BF measured by the commercial adipometer (TBF-607). The results validated also the efficiency of the belt type sensor system.

We present an open mobile platform that aims to benefit from versatile wireless sensors. This mobile assistant is a robot that can monitor different physiologic data for elderly people. Moreover it has the ability to determine the distance and potentially the position of the elderly person who use it. As an assistant it can transport some "objects" as glasses or drugs. Preliminary results show the proof of concept of our approach with a remote sensor that measures the temperature of the subject. We also present a method to assess the quality of the RSSI signal in order to determine the distance of a zigbee module attached to the arm of the subject. These results are the first steps towards a totally autonomous system that is an open platform. In this platform it will be easy to highlight the interaction or the correlation between the different physiological data and to move the robot properly in case of alert. It is possible to program different services and to integrate new sensors remotely. This platform can be convenient for developers and researchers involved in health technology.

Ambulatory sensor for the monitoring of the edema circumference in lower limbs

The monitoring of geometrical variations in segments of the human body is currently not widely used due to the lack of suitable devices. For lower limbs, for example, a simple measuring tape is generally used to periodically measure key dimensions. This measurement approach, and the associated lack of reproducibility, is not compatible with ambulatory monitoring and it is further recognized that precise, standardized reference points are required for the more meaningful monitoring of the lower leg. The paper presents the design and realization of a new sensor system dedicated to the measurement of geometrical variations in the lower limbs, enabling the ambulatory monitoring of leg edemic swelling during daily activity. The sensor is based on an inductive loop directly integrated into a textile band and connected to a miniaturized electronic system which sends, via wireless transmission, the perimeter value of the leg (assuming that its shape is circular) to a laptop and in the near future, to a mobile phone. The inductive loop has been modeled using Matlab to predict the inductance value and determine the necessary parameters of the electronic circuit. The portable, ambulatory device enables the measurement of perimeters ranging from 25 cm to 33 cm, with an accuracy of 0.3 cm. Stability of the sensor over the time is very good (3.4% of the full scale). Hysteresis occurs when the textile is stretched between two extreme values which can be minimized by regular calibration of the system. The presented results are significantly better than those currently obtained using the traditional measuring tape. (C) 2018 Elsevier B.V. All rights reserved.

Recent progress in biosensor technology and wearable devices has created a formidable opportunity for remote healthcare monitoring systems as well as real-time diagnosis and disease prevention. The use of data mining techniques is indispensable for analysis of the large pool of data generated by the wearable devices. Deep learning is among the promising methods for analyzing such data for healthcare applications and disease diagnosis. However, the conventional deep neural networks are computationally intensive and it is impractical to use them in real-time diagnosis with low-powered on-body devices. We propose Staged Inference using Conditional Deep Learning (SICDL), as an energy efficient approach for creating healthcare monitoring systems. For smart diagnostics, we observe that all diagnoses are not equally challenging. The proposed approach thus decomposes the diagnoses into preliminary analysis (such as healthy vs unhealthy) and detailed analysis (such as identifying the specific type of cardio disease). The preliminary diagnosis is conducted real-time with a low complexity neural network realized on the resource-constrained on-body device. The detailed diagnosis requires a larger network that is implemented remotely in cloud and is conditionally activated only for detailed diagnosis (unhealthy individuals). We evaluated the proposed approach using available physiological sensor data from Physionet databases, and achieved 38% energy reduction in comparison to the conventional deep learning approach.

Current mobile revolution is leading to an increase of wearable health devices development and consequently a growth in ambulatory monitoring area. These systems can be applied in ambulatory diseases management and diagnosis, personal health monitoring or sports performance enhancement, providing physiological and body-area ambiance data during daily normal activities. Nowadays several devices in the market have this type of technology, being one of them the VitalJacket (R) (VJ (R)), a product from Biodevices, S.A. This device is a medical certified smart t-shirt with textile embedded electronics for ambulatory monitoring of electrocardiogram (ECG), Heart Rate (HR) and Accelerometer (Acc) data that is in the market since 2008. In this work we report the result of a university-company joint R&D effort that aimed to propose a reference extension architecture - called VitalLogger - for VJ (R) wearable health device that enables sensors seamless "plug-in" to the company product. As a proof of concept of this novel adaptable architecture, we jointly implemented a prototype that extends VJ (R) technology to incorporate new sensing modules in a seamless way. Both hardware and firmware were re-designed and extended to create a reference extension architecture, enabling easy integration of different sensing modules according to the user monitoring preference/scenario. Besides the ECG module already incorporated in VJ (R), a module with a Blood Oxygen Saturation (SpO2) sensor and an ambiance temperature and relative humidity sensor was developed and added to the extended prototype VitalLogger. This prototype was successfully built and tested, showing excellent results. The VitalLogger adaptable extension architecture has shown its scalability by enabling seamless "plug-in" sensing modules thus creating the possibility of swift creations of new products with different sensors combinations to adapt to different monitoring scenarios.

Stimuli-responsive polymeric materials have attracted enormous interest in recent years due to their ability to generate temporary shape changes and recover their original shape in response to an appropriate stimulus [1-5]. smart polymers have seen rapid development with applications in a broad range of areas, such as aircraft, smart textiles, sensors, actuators, shape adaptive systems, and biomedical engineering. Actuation methods play an important role in utilizing smart polymers effectively. At present, solution-responsive polymers are becoming a focus of study to meet the requirements of applications in liquid media such as marine and physiological environments. Water-responsive polymers are desirable, as little energy is required to trigger shape recovery. For example, Huang et al. [6] have reported that water can actuate shape memory polyurethane into different patterns sequentially, and recover the original shapes in sequence. Reversible intermolecular hydrogen bonding is the reason behind these features. Wang et al. [7] have prepared a hybrid that responds to both temperature and water actuations. Humidity-induced, bendable Nafion-based smart textiles have been designed to reversibly adapt their insulation functionality. smart clothes are currently a hot topic in smart materials. The future prospects and range of applications for these materials are wide-reaching, and will attract attention from interested readers in a broad range of fields. Nafion known as smart polymers which exhibit shape change and shape recovery properties in response to heating and humidity stimuli.[8-10] When humidity increases, as might occur during human sweating, the pre-cut flaps open to produce pores in the polymer sheet and permit air flow through the open pores, thus reducing both the humidity level and apparent temperature. If the bendable polymer sheet is inserted between two fabrics,, therincreasing humidity attenuats the inserteby reducing the gap between the two fabrics to
