摘要：
A composition is disclosed which forms a bend sensor when coated on a flexible substrate. A bend sensor prepared from the composition is also disclosed. The composition contains a brittle binder which cracks under a stress, electrically conductive elements and a graphite additive which stabilizes the degree of cracking. The composition forms a bend sensor which upon a change in degree of flexing produces an electrical signal in the form of a change in resistance in circuits which include the sensor.
