BAND SENSOR

摘要

PURPOSE: A bending sensor is provided to implement accurate sensing based on the contact of connection terminals. CONSTITUTION: A bending sensor(10-1) comprises a bending sensor body(20) and a determination circuit(30). 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 body comprises an upper plate(21) which is flexible and has a plurality of first connection terminals(25) arranged at regular intervals and a lower plate(23) which has a plurality of second connection terminals(27) located to contact the first connection terminals. One of the first connection terminals is fixed as being connected to one of the second connection terminals. In case the bending sensor body is not bent, the rest of the first connection terminals are respectively connected to the rest of the second connection terminals. In case the bending sensor body is bent, at least one of the rest of the first connection terminals is not connected to at least one of the rest of the second connection terminals.
