Abstract
A sensor for angle measurement of a joint is disclosed. The sensor comprises a code strip, a linear encoder configured to detect relative movement between the linear encoder and the code strip, and a microcontroller configured to compute angular rotation of the joint from linear displacement obtained by the relative movement. The relative movement corresponds to rotation of the joint. A corresponding method and system are also disclosed.

A method for angle measurement and motion capture of a joint, the method comprising:
- attaching a sensor to a joint;
- effecting relative movement between a linear encoder and a code strip in the sensor, the relative movement corresponding to rotation of the joint;
- converting electrical signals from the linear encoder arising from the relative movement into position information and rotational angle of the joint.
