Title:
MOVEMENT ACTUATOR/SENSOR
Document Type and Number:
Japanese Patent JP3824329
Kind Code:
B
Abstract:
PURPOSE: To obtain a device which detects the movement of a microstructure element, including its extent and direction by moving a fiber adaptively to the shape variation of an operable material, in response to an operation signal for varying the shape.
CONSTITUTION: A rod 92 of the detecting device has one end fixed to a base 102 and a strain gauge 110 generates a signal having a level indicating the quantity of strains generated at the position of the strain gauge in the circumferential direction around the rod 92. When the rod 92 is bent by a force applied at its free end, the rod is strained in various states at various positions around the rod along the circumference, which is detected at least the position of the strain gauge 110, so that the signal indicating the quantity of the strain is supplied to a microprocessor 114. The microprocessor 114, on the other hand, calculates the direction and degree of the bending of the rod 92 from the signal received from the strain gauge 110.
