Special Issue Information

Dear Colleagues,

Flexible or wearable bio/chemical sensors that attach to body accessories or human skin have been given great attention because of the popularization of portable electronic consumers, including implantable/attachable medical analyzing or various smart electronics (sports watches/bracelets). The latest developments in materials science, mechanics technology, and electronics can help in establishing the various stretchable and flexible sensing devices (e.g., electronic skin) conforming to the complex, textured surface of the skin or clothing. At the same time, the rapid development of self-powered techniques has also brought enormous opportunities for the advancement of traditional sensing systems. Integrating different power-generating devices into the system is becoming a critical component for constructing a self-powered flexible biosensing or chemical-sensing system. The convergence of wearable electronics, miniaturized sensor technologies, and self-powered techniques provides novel opportunities to improve the quality of health/environmental analysis while realizing private, accurate, real-time bio/chemical sensing. This series of works will be very interesting and beneficial to the scientific community to develop the next generation of bio/chemical sensors and expand the scope of self-powered systems.

With the development of 5G technology, contemporary technologies such as Internet of Things (IoT) and Big Data analyses have been widely applied to the sport industry. This paper focuses on the design of a portable, self-powered, flexible sensor, which does not require an external power supply. The sensor is capable of monitoring speed skating techniques, thereby helping professional athletes to enhance their performance. This sensor mainly consists of Polyvinylidene Fluoride (PVDF) with polarization after a silvering electrode and a flexible polyester substrate. Flexible sensors are attached to the push-off joint part of speed skaters and the ice skate blade. During motion, it produces different piezoelectricity signals depending on the states of motion. The monitoring and analyzing of the real-time sensor signals will adjust the athlete’s skating angle, frequency, and push-off techniques, thus improving user training and enhancing performance. Moreover, the production of piezoelectric signals can charge the capacitor, provide power for small electronic equipment (e.g., wireless device), and extend the applications of wearable flexible sensors to the Big Data and IoT technologies in the sport industry.
