Bend sensor
A bend sensor includes a flexible circuit substrate, an insulation pad and a flexible conductive substrate. The flexible circuit substrate includes an insulating body, a first circuit and a second circuit. The first and second circuits are disposed on opposing sides of the insulating body. The first circuit has first fingers, while the second circuit has second fingers. The insulation pad disposed on the insulating body exposes the first and second fingers. The flexible conductive substrate disposed on the insulating pad has a conductive layer separated from the first fingers and the second fingers. While the bend sensor is bent, the conductive layer on the flexible conductive substrate would deform toward the flexible circuit substrate so as to form multiple contacts with the first and second fingers. Through these contacts, a number of resistors are formed to contribute a detectable resistance for the corresponding bending amplitude to be further realized.
