Recent progress on the wearable devices based on piezoelectric sensors

Abstract

This paper reviews recent progress on the wearable devices based on piezoelectric sensors. In recent years, many researches have turned eyes to the studies of wearable devices based on piezoelectric sensors because of the sensors' high sensitivity and efficiency. In addition, on account of their numerous advantages, the piezoelectric sensors have made great progress in medical monitoring domain. In this paper, the latest development for the use of piezoelectric sensors in medical devices will be reviewed briefly. The working principle of the piezoelectric sensors will be given. And then, the body parts that can be used for medical monitoring will be illustrated. After that, wearable medical devices made of different materials will be discussed, and their strengths and weaknesses will be analyzed. Finally, all the work listed in this article will be summarized and the future of piezoelectric sensors in the field of medical equipment will be expected.
