Nowadays, the integration of smart sensors in wearable affective computing systems aims to improve and create applications based on conventional sensing technology. The inclusion of this type of sensors is key in high sensing-demanding applications, such as those based on affective computing. This sensing integration must be quantitatively supported by metrics that directly affect performance, such as processing time, memory usage, and measurement accuracy. This paper presents a comprehensive analysis of a specific smart sensor integration in a wearable constrained device from an embedded perspective. The authors performed this implementation by considering BINDI, which is a wearable device developed by the UC3M4Safety research group to prevent gender violence situations. BINDI monitors user physiological and physical variables to detect fear through artificial intelligence algorithms. Along with other sensors, this device incorporates an electroDermal activity (EDA) sensor. This type of sensor was proven to be a valuable source of information directly related to the autonomous nervous system (ANS) activation, which regulates physiological responses in stress and relaxed affective states. In the initial version of Binode, which was validated in different experiments with different volunteers, the EDA sensor is based on a DC measurement schema. However, AC measurement EDA circuitry is known to provide a higher amount of information. Thus, this work presents a detailed comparison between the current EDA sensor and a specific AC smart EDA sensor for a future version of BINDI.

Wearable sensors provide the capability to noninvasively monitor physiological parameters during spaceflight, including those related to physical performance and daily activity. Regular monitoring of general health and exercise capabilities in astronauts can ensure adequate performance levels and record health changes caused by the space environment. Relevant measurables include vital signs, cardiovascular health, and activity monitoring. Wearable sensor devices can be comfortable for long-term use and easy to operate, which is particularly important during more autonomous future planetary missions. Many devices are currently being developed and tested, but few wearable devices or integrated “smart” garments have been assigned for regular use on the International Space Station. The unique needs of the space environment must be considered to facilitate the development and implementation of wearable devices, particularly “smart” sensor garments, for space applications.

Due to the mobility and openness of wireless body area networks (WBANs), the security of WBAN has been questioned by people. The patient's physiological information in WBAN is sensitive and confidential, which requires full consideration of user anonymity, untraceability, and data privacy protection in key agreement. Aiming at the shortcomings of Li et al.'s protocol in terms of anonymity and session unlinkability, forward/backward confidentiality, etc., a new anonymous mutual authentication and key agreement protocol was proposed on the basis of the protocol. This scheme only uses XOR and the one-way hash operations, which not only reduces communication consumption but also ensures security, and realizes a truly lightweight anonymous mutual authentication and key agreement protocol.

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

The process of photosynthesis implies the transformation of light into chemical energy in photosynthetic organisms. One of the procedures of utilizing the light reaching the plant leaf for chemical energy production is via the chlorophyll (CF) molecules that enable biochemical processes. Chlorophyll fluorescence measurement technique is used to assess the photosynthetic performance of plants and the main principle is based on light energy distribution. Although the plant physiological status is monitored and influenced with agricultural practices like crop rotation and fertilization, various deviations might happen in the agro-ecosphere. Fluorescence transient is monitored through different parameters like maximum fluorescence and different states of dark-adapted fluorescence are measured. Fluorescence is commonly measured using fluorometers like Pocket plant efficiency analyzer (PEA) and Handy PEA. Novel solutions include satellite observations and IoT solutions. Cost-efficient solutions based on a single sensor node provide less accuracy, while sensor networks acquire results comparable to reference data. This short review presents an overview of available sensors, methods and algorithms for measurements of chlorophyll fluorescence and identifies open issues and research directions for the future work.

Commercially available, wearable physiological monitors rely on rigid, multiple electronic components, coupled with aggressive adhesives and conductive gels, often causing discomfort and skin breakdown. Here, we introduce an all-in-one, wireless, stretchable bioelectronics platform for portable, real-time physiological monitoring and accurate classification biopotentials, including electrocardiograms (ECG), electroencephalograms (EEG), and electromyograms (EMG). The nanomembrane sensor and multi-layered electronic system is manufactured by integration of microfabrication techniques, aerosol jet printing of nanoparticles, photonic sintering, and hard-soft materials assembly. Strategic integration with hyperelastic elastomers allows the device to adhere and deform naturally with human body while maintaining the functionalities of the on-board electronics. Stretchable electrodes with optimized structures for intimate skin contact acquire high-quality biopotentials. Comparison of those signals with commercial systems captures the improved performance and significant noise reduction of the stretchable bioelectronics. Implementation of convolutional neural networks for real-time classifications of ECG, EMG, EEG and inertial measurement data demonstrates the feasibility for precise control of external systems. In vivo demonstrations with human subjects in various scenarios reveal the versatility of the device as both a health monitor with real-time cardiac monitoring and a viable human-machine interface.

The wireless body sensor network (WBSN) is an emerging technology in the healthcare domain, which collects data from vital parameters of the patient's body, using small portable components such as sensors. It allows to continuously monitor patients without restricting their movements and to inform the health specialist of the evolution of their states. However, the deployment of new technologies in health applications without taking into account data security makes the privacy of patients vulnerable. Thus, these systems have insufficient performance for large and varied data sets, because they do not process information sufficiently diverse to cover all scenarios. Moreover, the interpretation of physiological signals is a tedious process in which human errors can be *** address these issues, we propose, in this paper, an effective health system that ensures the secure collection and transfer of patient data to the physician, to facilitate the diagnosis and the detection of life threatening diseases. Our main contribution is to offer real-time, high quality processing, learning and analysis capabilities, in a smart and secure system. For that, we have collected real patient datasets from Tunisian *** achieve this goal, we used ANN and XgBoost as learning algorithms and AES as an encryption protocol for sending secure data to medical personnel for diagnostic purposes. The results show an accuracy of 80% with an execution time of 1.54 s.

Recently there is a big thrust on bio-inspired sensors and there has been a large rise in the investment and expectations for nanotechnology to meet these goals. For in situ sensor development materials deposition on substrate is essential part of device development. Physical vapor deposition (PVD), chemical vapor deposition (CVD) and molecular organic vapor deposition methods have developed for growth of semiconductor bulk and thin film growth with some modifications have been used for these materials. Oxides and other elements of VI group such as sulfides and selenides are key components in skins of many species. Growth of ordered structures containing these elements have been achieved by using PVD method. This paper describes effect of growth parameters during PVD growth on the quality of materials. Growth kinetics and mechanism will be discussed for the vertical and horizontal growth reactors. Since most of the efficient materials systems are multinary and in many cases non-congruent, PVD provides pathway to grow materials below melting temperature.
