The wearable devices are gaining its popularity in recent years. This paper presents the performances of our smart shoes as a wearable biomedical device in capturing the heartbeat signal from dorsalis pedis. Generally, the heartbeat measured from an artery was located on the chest, hand, fingertip, and ear or neck. Even though the pulse from dorsalis pedis has a smaller amplitude compared to the other artery location, the integrated sensor on our smart shoes can capture the signal with high precision. The experiment was conducted several times to three groups of healthy participants; they were kid, mature, and elder. The results show that the smart shoe sensor could measure the dorsalis pedis pulse and has a maximum error rate of 11.76% compared to the digital tensimeter. Unlike the standard measurement and other commercial devices, our device gives a small gap in RMS error, which is acceptable for clinical needs.

Physical exercise has proved benefits for general health [1] and can reduce the number of sports injuries to one third [2]. However, an athlete that has been injured during sports practice may omit this out of fear of discrimination, and worsen the injury in the weight room, during strength training [5]. Monitoring physiological status of an athlete or rehabilitation patients during training may thus help the person to get an earlier intervention, preventing injuries from getting worse. With this in mind, we propose a set of compression garments - shirt and leggings - with textile sensors to continually monitor heart and muscle activity, breathing rate and temperature. This paper reports the design of the garments and production of the shirt, which comprised a 3-lead ECG system, sEMG (Surface Electromiography) electrodes and a breathing sensor. The ECG (Electrocardiography) system was tested and presented some good results, in particular for very even movements, but the system still needs to be improved, in order to get a better signal, when it comes to movements with a considerable amplitude.

Multi-channel physiological signal measurement systems that are available at the moment are usually wired ones, such as the BioPack MP150 system. The latter, however, is known for its huge size, required connection to alternated current power, lack of an independent data storage unit, and lack of wireless transmission. This study aims to develop a portable wireless physiological signal measurement system that consists of 8 channels. With TI MSP430 F5438A at its microcontroller unit, it had a compact size, lithium battery to supply the needed power, Bluetooth 3.0 data transmission, and built-in 2G flash memory, and the signals were showed on a tablet, smart phone or a notebook computer concurrently. Meanwhile, it also supported the extra power supply, ±3V for the other measurement modules. Researcher could use a self-made sensor circuit, and combined with this system to do the ubiquitous healthcare studies.

Several studies have been proposed to estimate blood pressure (BP) with cuffless devices using only a Photoplethysmograph (PPG) sensor on the basis of the physiological knowledge that the PPG changes depend on the state of the cardiovascular system. In these studies, machine learning algorithms were used to extract various features from the wave height and the elapsed time from the rising point of the pulse wave to feature points have been used to estimate the BP. However, the accuracy is still not adequate to be used as medical equipment because their features cannot express fully information of the pulse waveform which changes according to the BP. And, no other effective knowledge about the pulse waveform for estimating BP has been found yet. Therefore, in this study, we focus on the autoencoder which can extract complex features and can add new features of the pulse waveform for estimating the BP. By using autoencoder, we extracted 100 features from the coupling signal of the pulse wave and from its first-order differentiation and second-order differentiation. The result of examination with 1363 test subjects show that the correlation coefficients and the standard deviation of the difference between the measured BP and the estimated BP got improved from R = 0.67, SD = 13.97 without autoencoder to R = 0.78, SD = 11.86 with autoencoder.

sensorized robot skin has considerable promise to enhance robots' tactile perception of surrounding environments. For physical human-robot interaction ( pHRI) or autonomous manipulation, a high spatial sensor density is required, typically driven by the skin location on the robot. In this study, two flexible sensor arrays with different densities (i.e., 4x4 and 11x11 skin arrays) are printed and packaged onto Kapton sheets and silicone encapsulants. To address scalability, sensitivity, and calibration challenges, a novel electronic module, free of the traditional signal conditioning circuitry was created. The electronic design relies on a software-based calibration scheme using high-resolution analog-to-digital converters with internal programmable gain amplifiers. In this paper, we show the efficacy of the proposed method with the 4x4 skin array using controlled pressure tests, and then perform procedures to evaluate each sensor's characteristics such as dynamic force-to-strain property, repeatability, and signal-to-noise-ratio. In order to handle larger sensor surfaces, an automated force-controlled test cycle was carried out. Results demonstrate that our approach leads to reliable and efficient methods for extracting tactile models for use in future interaction with collaborative robots.

Hemoglobin is the protein molecule that binds oxygen in the blood. Hemoglobin level can be used as a benchmark of the human physiological condition, such as anemia, hypoxia, and postoperative bleeding. Generally, measurement of hemoglobin levels is performed by an invasive method that takes blood samples to be tested. This study offers a tele-monitoring system for measuring the hemoglobin level non-invasively, so it could reduce the possibility of infection or contamination to the body and can be monitored anywhere by using a website. This tele-monitoring device of non-invasive hemoglobin and oxygen saturation levels were designed by integrating the pulse oximetry sensor with signal conditioning circuit, Arduino Uno as a microcontroller, Ethernet module, an internet network, cloud server, and website. Pulse oximetry measured the oxygen saturation in the blood that indicate the vital state of human and became essential to determine the amount of hemoglobin level. The system performance in this study was tested on participants who had a good daily exercise and participants who never had daily activities to discover the correlation between hemoglobin levels with human physical activity and obtained 89% of accuracy. This system can be implemented as a personal device for monitoring the hemoglobin level and the oxygen saturation in daily used.

We present a new head mountable wireless fiber biophotometry microsystem conceived to detect fluorescent signal fluctuations correlated with neuronal activity. The proposed system incorporates all aspects of a conventional tethered fiber-based biophotometry system encompassed into a wireless microsystem. The interface includes an LED as excitation light source, a custom designed CMOS biosensor, a multimode fiber, a microcontroller (MCU), and a wireless data transceiver enclosed within a 3D-printed, small and light weight, plastic housing. Precisely, the system incorporates a new optoelectronic biosensor merging two individual building blocks, namely a low-noise sensing front-end and 2 nd order continuous-time Σ Δ modulator (CTSDM), into a single module for enabling high-sensitivity and high energy-efficiency photo-sensing. The proposed CMOS biosensor is implemented in 0.18- μ m CMOS technology, consuming 41 μ W from 1.8- V supply voltage, while achieving a peak dynamic range of 86 dB over a 50- Hz input bandwidth at a 20-kS/s sampling rate. This new interface opens new avenues for conducting in-vivo experiments with live animals. © 2018 IEEE.

smart fabric technology (SFT) makes easier to monitor physiological parameters. smart Fabric technology or An electronic textile (e-textile) is prepared by incorporating wearable systems along with sensors deployed for body parameters which are used by doctors as markers to summarize health status. Such existing systems are battery driven and required cumbersome maintenance. It is the main cause for limited life span and lack of biocompatibility. These limitations are well addressed by proposing energy harvesting device (EHD) as an alternative to battery. It is basically an energy transduction mechanism in which vibration energy converted to useful electrical energy. This work focuses on low cost fabrication of EHD to make SFT self powered. The fabricated device is built out of polymer substrate, silver electrodes and zinc oxide as piezoelectric material. The devices have been characterized and found electric potential of 2.51Vpeak, 0.76Vrms whereas power was 12.61 mu Wpeak, and 1.18 mu Wrms for 500K Omega load at 53Hz peak resonant frequency. The power demand of commercially available cardiac sensor, adaptive pace maker, pulse oxymeter, sensor node demand power in the range of 1 mu W to 100 mu W. This reveals feasibility of energy harvester as an power source for SFT. Array of series and parallelly connected EHD can be deployed for fulfilling demand of integrated SFT.

physiological condition monitoring is an indispensable part of comatose patient treatment. Unfortunately, the bedside monitor, a tool which is commonly used to detect the patients' vital sign is only readable by medical officers and need to be observed at a close distance. This research focuses on the development of a system which enables comatose patients' family to read the vital signs effortlessly without having to be continually around the patients who are hospitalized in intensive care units (ICU). The system monitors the number of heartbeats, respiratory rate, and detects eyelid opening using pulse sensor, thermistor and Infrared Light Emitting Diode (IR LED) respectively. All data acquired from the sensors are sent to the database and displayed on Android devices. A special notification is given to family members as well as medical officers when an anomalous condition is detected. From experiments, it can be concluded that the system can monitor patients' physiological condition and send a notification when abnormal ailment happen with 94% accuracy.
