The bend sensors are a long strip of flexible plastic whose electrical resistance changes as it is bent. They were originally developed by the Nintendo Corp. for a device they sold called the Power Glove. Bend sensors were sewn into the fingers of the glove, enabling wearers to control action in a video game by flexing their fingers. Venus Fly Trap used bend sensors to simulate the filaments of a flower. When a bug was sensed wiggling the filaments, Fly Trap would close its mighty jaws. We also have a sample of a “skin sensor” material, which is similar to the bend sensor, but respond more to gentle stroking than to bending.
