  • System and method for force feedback
    Patent number: 7438724
    Abstract: A system and method of grip force feedback for use with a prosthetic device is provided in the present invention. The system can include a prosthetic hand having a plurality of digits for use with the prosthetic device. A force sensor can be provided to produce a force signal and the force sensor is configured to be associated with the plurality of digits for the prosthetic hand. In addition, a force feedback controller can receive the force signal from the force sensor. A force feedback actuator is also in communication with the force feedback controller. The force feedback actuator can provide feedback vibrations to a user of the prosthetic device.
