Wearable and Flexible Heart Pulse Sensor Integrated with a Soft Pump and Actuator

This study proposes a wearable and flexible heart pulse sensor detected from a wrist using the tactile pressure sensor film. In general, it is difficult to monitor heart pulse stably under movement of wrist due to the change of position and pressure of the sensors on a wrist. To address this issue, soft pneumatic pump and actuator are integrated to fix the sensor on a wrist even under movement of body. Fundamental properties of pneumatic pump and tactile pressure sensor are studied in addition to the heart pulse monitoring.
