Abstract
A force sensing device is mounted on a tool to sense force, particularly quasi-static and static forces. The force sensing device includes at least one a sensor. A piezoelectric element in the sensor includes a driving portion and a sensing portion. A first voltage is input to the driving portion to generate a vibration in the piezoelectric element and a second voltage in response to the vibration is output from the sensing portion. The second voltage output from the sensing portion is changed as the vibration in the piezoelectric element is suppressed by an external force acting on the force sensing device so variation of the second voltage can be used to measure the external force.
