Abstract
A collision detector includes a deformable portion and a planar sensor accompanied by a process circuit and a collision determination unit. The deformable portion is configured to be deformed on a collision on an object. The planar sensor has a planar coil formed as a planar winding of winding wire to be deformed along the deformation of the deformable portion. The process circuit generates an electric signal that is in proportion to a self inductance Ls of the planar coil. The collision determination unit determines whether the object collided with the deformable member based on the change of the electric signal.
Claims11
A collision detector comprising:
- a deformable member capable of being deformed on collision;
- a planar sensor having a coil in a planar shape to be bent by deformation of the deformable member, wherein the coil in the planar shape is formed with its winding wound in a plane;
- a process circuit capable of generating an electric signal in proportion to a self inductance of the coil in the planar shape;
- and
- a collision determination unit capable of determining the collision of the deformable member based on change in the electric signal.
