1. An array of bending and/or stretching electromagnetic energy sensors to measure movement of a body joint comprising:
- a first longitudinal electromagnetic energy sensor which is configured to longitudinally span a body joint, wherein this first longitudinal sensor spans the body joint within a first radial quadrant of the body joint, and wherein the first longitudinal sensor is configured to bend and/or stretch when the body joint move;
a second longitudinal electromagnetic energy sensor which is configured to longitudinally span the body joint, wherein this second longitudinal sensor spans the body joint within a second radial quadrant of the body joint, and wherein the second longitudinal sensor is configured to bend and/or stretch when the body joint moves;
a third longitudinal electromagnetic energy sensor which is configured to longitudinally span the body joint, wherein this third longitudinal sensor spans the body joint within a third radial quadrant of the body joint, and wherein the third longitudinal sensor is configured to bend and/or stretch when the body joint moves;
a fourth longitudinal electromagnetic energy sensor which is configured to longitudinally span the body joint, wherein this fourth longitudinal sensor spans the body joint within a fourth radial quadrant of the body joint, and wherein the fourth longitudinal sensor is configured to bend and/or stretch when the body joint moves; and
a plurality of radial electromagnetic energy sensors which are configured to collectively span the body joint, wherein the longitudinal axes of the radial electromagnetic energy sensors converge;
wherein changes in electromagnetic energy transmitted through the first longitudinal electromagnetic energy sensor, the second longitudinal electromagnetic energy sensor, the third longitudinal electromagnetic energy sensor, the fourth longitudinal electromagnetic energy sensor and/or the plurality of radial electromagnetic energy sensors are measured as the body joint moves.

Abstract
This invention is a sensor array which longitudinally spans a body joint in order to measure movement of that body joint. In an example, this sensor array can comprise four longitudinal sensors which span the body joint in four different radial quadrants, respectively. In an example, this sensor array can comprise six longitudinal sensors which span the body joint in six different radial hextants, respectively. In an example, this sensor array can further comprise a first accelerometer which is proximal to the body joint and a second accelerometer which is distal to the body joint.
