BEND SENSOR BY USING RESISTIVE BALLS

摘要

PURPOSE: A bending sensor using spherical resistances is provided to recognize transformation by measuring the resistance values of the spherical resistances. CONSTITUTION: A bending sensor comprises a bending sensor body(30) and a determination circuit(20). The determination circuit determines the degree of transformation of the bending sensor body from changes in the resistance value of the bending sensor body. The bending sensor main body comprises a plurality of spherical resistances having respective resistance values, an outer shield which surrounds the spherical resistances, and a plurality of pads which are located at regular intervals on each plane of the outer shield. The resistance value of the bending sensor body changes according to the contact between each pad and the spherical resistances.
