How about a grip capacitor?

Grip Capacitor is good.

Handshake capacitance is a capacitive sensor with high sensitivity to detect small pressure changes, so it is widely used in touch screen, gamepad and other fields. Compared with other sensors, handgrip capacitance has lower noise and can provide clearer signal output. Moreover, the simple structure of the handshake capacitor is easy to install and can be adapted to different application scenarios.

Handshake capacitors are also characterized by fast response time and good durability. Due to its high sensitivity and fast response speed, it is widely used in the field of gamepad, medical equipment and so on.
