Abstract: In a near future, many people will be able to visit and stay in the space hotels easier than now days. In this situation, a novel clothes that fit to the special environment will be required. In this paper, we describe the detail of a prototype of “space clothes”, a new clothes design that could solve the appearance and functionality conditions shown below.Conventional clothes especially skirts and loosely designed shirts are often difficult to be worn in space because it restricts wearer’s motion. On the other hand, such clothes are often preferred by women because of their elegance. The both elegance and functionality must be achieved for the clothes of the future space tourists.All the future space tourists should suffer from space sickness and sunburns by ultraviolet rays. Those issues will worsen the experience in the space. Future clothes for space tourists should be able to solve or be able to mitigate them. Based on these conditions, we developed a prototype of clothes for future space tourists(Figure 1(a)). This clothes is carefully designed to achieve both functionality and elegance. In addition, it embedded with bio-informatics display system to share wearer’s health status among other tourists to enable early initial treatment(Figure 1(b)). We believe that this paper could be a good opportunity to initiate the discussion to clear new market of clothes in space.

Abstract: Wireless Body Area Network or known as BAN, is a system consists of various kinds of wearable sensors to measure condition of human body. Wrist, waist and shoulder modules from BAN system can help to monitor, analyze and provide advice to the user in order to perform a moderate exercise. The availability of small, low-cost networked sensors combined with advanced signal processing and information extraction is driving a revolution in physiological monitoring and intervention. BAN system is enabling technologies for accurate measurements in healthcare systems, enhance sports and fitness training, life-style monitoring and individualized security.

Abstract: This paper describes a wearable technology sub-health monitoring system based on the description of the system and physiological signals by Zigbee module sub-health data collection, acquisition and transfer process, as well as PC using BP neural network for sub-health algorithm model state assessments; simulation tests to verify the rationality and practicality of the system. In short, the system has a simple and accurate calculation of benefits for sub-health can quickly assess and provide comprehensive, objective and scientific decision-making reference, extensive prospects.

Abstract: In recent years, there has been significant progress in a number of sensing technologies related to on-body measurements, such as platforms for monitoring respiration, heart rate, location and movement. In these cases, the sensing element (s) are based on highly effective transducers that are increasingly integrated into garments such that they are becoming innocuous to the user. In contrast, the area of on-body chemical sensing remains highly under-developed. In this paper, we will address the significant challenges that are inhibiting the practical realisation of reliable chemical sensors and biosensors capable of generating accurate data in real time.

Abstract: A design of capacitor-coupled ECG test system is introduced here. The extremely weak ECG signal was picked up with capacitor coupling sensor, and was then buffered, filtered and magnified to fit the requirement of analog digital converter. The measured data was then converted and processed by a microcontroller. The ECG signal can be recovered and stored, analyzed by intelligent terminal. The test shows that this method is applicable and would be used widely.

Abstract: Similar to many other countries in the world, the elderly population in Taiwan is now growing rapidly. Some older adults are found to have difficulty controlling their emotion, which may later develop into psychological diseases such as anxiety disorder. Therefore, emotional control is an important issue for elderly citizens. This study proposed a wearable biofeedback emotional control device, FeelVest, which integrates electrocardiography acquisition with heart rate variability analyzing techniques to detect user’s emotion. When a user is nervous and unstable, FeelVest would analyze the emotional state of the user. If the user’s emotional condition is judged as abnormal, the control module would remind the user to relax through vocal notification, or broadcast relaxation melodies to ease the user’s nerve. With this vest, older adults are able to monitor and regulate their own emotion and have a healthier life style.

Abstract: Wearable, textile-based antennas are dominated research topics for body-centric communications because it could be easily worn on body and integrated into clothes. Since the antenna will operate on a moving person, a circularly polarized antenna is needed in order to optimize the off-body communication link. A wearable circularly polarized textile antenna for body-centric wireless communications is designed in this paper. The proposed antenna is a square-ring microstrip antenna with truncated corners with the bandwidth of 9% when off the body. When it is near the body, we simulate the human body as three-layer model including skin, fat and muscle and put the antenna at different distances to the body. The situation of antenna bending is also simulated at different radii. Specific Absorption Rate was evaluated at last.

Abstract: The development of Micro-ElectroMechanical Systems ,integrated circuits, wireless communications have resulted in the creation of miniature, ultra-low power, and wearable health monitoring system. The system can be defined as a Body Sensor Network that can be embedded in the user’s outfit as a part of the clothing .This 3ACare system is a wearable health monitoring and alert system which can give anyone health care at anytime and anywhere. The system continuously collects multiple vital signs by physiological sensors and evaluates the signs in a personal server such as a PDA. And the personal server transfers the data to a medical server center by 3G net or Internet. The doctor in the medical server center will give the patients message after they diagnosed the data.The paper describes the architecture of 3ACare and the details of the wireless body sensor network (WBSN) nodes and the test result.

Abstract: In this paper we present a new compact and portable rehabilitation system. It's role is to provide therapeutic passive motions of the hand. The anatomical characteristics and the biomechanics of the wrist are emphasized. The target anatomical movements of the hand are flexion-extension and abduction-adduction. A comparative study of similar devices is presented. The principle of operation of chosen variant is given. Its design methodology is detailed. A functional prototype was developed and its functional parameters are presented.

Abstract: Continuous health monitoring often requires hospitalization, which can become an expensive and inconvenient choice for the patient. In this perspective, wearable sensors that allow in situ biosensing constitute a very promising technology. This work aims to develop immunosensors for continuous monitoring of the wound healing process, based on pH changes, as well as on the concentrations of inflammatory proteins such as the C-reactive protein (CRP). Sensing principles include the use of responsive hydrogels that swell in response to changes in the surroundings, and the use of functional surfaces that specifically recognize the target protein. The detection principle is based on an optical signal, using the evanescent field of light propagating along a waveguide, probing refractive index changes. An optical sensing system that can be integrated in a wound dressing patch has been designed, including a white light source (LED), and a spectrometer for detection. The sensor was successfully tested in the laboratory with biological samples (blood serum), demonstrating reversible pH measurements between pH 6-8, and detection of changes in the concentration of CRP between 1 and 100 μg/ml. The sensor will later be integrated into wound dressings or bandages, forming a sensing patch that is connected via optical fibres and electrical wires to the detection system and power supply. This novel technology will be particularly valuable in applications such as the supervision of skin grafts and ulcer treatments.
