Patent ID: 8880358

Claim:
A sensing device for measuring movement of a moving segment of a body relative to a reference segment of the body, the sensing device comprising: a covering configured to be positioned in contact with the body, the covering including a first covering portion and a second covering portion; wherein the first covering portion is configured to be positioned in contact with the moving segment of the body, and the second covering portion is configured to be positioned in contact with the reference segment of the body; a sensor operatively attached to the second covering portion; a triggering mechanism operatively attached at a first end to the first covering portion, and operatively connected at a second end to the sensor; wherein the triggering mechanism extends from the moving segment to the reference segment and across a joint center located between the moving segment and the reference segment when the covering is positioned in contact with the body; wherein the sensing device is configured such that when the covering is positioned in contact with the body, movement of the moving segment activates the triggering mechanism to provide a force input to the sensor; wherein the force input actuates the sensor to generate an output defining at least one measurement of the movement of the moving segment.
