“…In this paper, we use two techniques to solve these problems. Different from the traditional sensing circuit, a mechanically optimized circuit structure is demonstrated to make the system more extensibility and flexibility [18,19]. The circuit powering system is also optimized because of the material development [20,21].…”

Hands are the most useful organ in our daily life while the monitoring of hand action still lacks report until now. The monitoring and analysis of human hands will benefit the development of medical science, automatic robots, and human action analysis. Here, we build a non-battery system to monitor human hands. The system is fixed on a glove with five flexible sensors on each tip of the finger to monitor the pressure on these positions and a hard in the center to collect power and drive the circuits. Furthermore, after the mechanical analysis, a specially designed S shape structure is used for the lines in this system to make it have more movement room and robustness. The final system is used in the monitoring of basketball games with the center part pad to collect the energy and the sensitivity of the sensor is measured as 0.04 V/N. Four actions on hand in a basketball game are measured and the pressure on four fingers is analyzed, showing the force distribution of each finger. This work demonstrates that the design can be used in the analysis of hand movement to make an innovation to the sensing of the human body.
