One approach to collect such information is a wearable and flexible device, which detects information from the skin surface. An important dataset is heart pulse information. Herein a method to monitor the detailed pulse signal from a wrist stably and reliably is proposed. Specifically, a soft pneumatic balloon operated by a soft pump applies the appropriate pressure over a tactile sensor onto the radial artery of the wrist to detect detailed heart pulse waves. The soft pump, pneumatic balloon, and flexible tactile pressure sensor are characterized as a fundamental study. Additionally, a proof-of-concept of this integrated device platforRSC advancesWrist flexible heart pulse sensor integrated with a soft pump and a pneumatic balloon membrane.PMC9057701JP18H05472JPMJPR17J5JP17H04926Arie TYamaguchi TAkita SYamamoto DTakei KfalseWrist flexible heart pulse sensor integrated with a soft pump and a pneumatic balloon membrane.To monitor health and diagnose disease in the early stage, future healthcare standards will likely include the continuous monitoring of various vital data.
