Abstract:
A flexure measurement device measures the flexure of a flexing body part thereby describing a range of motion of the body part. The flexure measurement device includes a flexible member and a sensor for detecting a change in proportion of the flexible member in response to flexing of the flexible member. In one example, a flexure measurement device measures a change in a length dimension of an elongated flexible member. The length dimension is measured using transmitted signals in which a light source directs a light beam across an array of light sensors. A change in length causes a light source to pivot, thereby changing the light sensors upon which the light beam impinges. The flexure measurement device determines a position in the array of light sensors at which the illumination changes from light to dark to produce a flexure angle measurement.
