Abstract:

This paper reports a flexible pressure sensor based on electroplated-Ni film induced mechanical cracking that realizes the resistance change once undergoing pressure. A lot of cracks will be induced at the tip of triangle patterns due to the stress concentration when the sensor is pressed, which results in the resistance change with pressure. The test results show that the gauge factor of the fabricated pressure sensor reaches a maximum gauge factor of 24.2482 kPa-1 at 30.84 kPa. The fabricated pressure sensor has a response time of 18 ms and can even be applied in the wearable devices application, such as pulse detection.
