Joint Angle Tracking With Inertial Sensors US 20090204031 A1

A method for estimating joint angles of a multi-segment limb from inertial sensor data accurately estimates and tracks the orientations of multiple segments of the limb as a function of time using data from a single inertial measurement unit worn at the distal end of the limb. Estimated joint angles are computed from measured inertial data as a function of time in a single step using a nonlinear state space estimator. The estimator preferably includes a tracking filter such as an unscented Kalman filter or particle filter. The nonlinear state space estimator incorporates state space evolution equations based on a kinematic model of the multi-segment limb.

Sensing Bending Of Multiple Joints US 11494147 B2

Examples are disclosed that relate to sensor devices configured to sense bending in multiple joints. One example provides a sensor device configured to span a first articulable joint and a second articulable joint. The sensor device comprises a plurality of electrodes arranged in a stack and connected to a base. The plurality of electrodes comprise a first electrode arranged at a first joint region of the sensor device that is configured to be positioned at the first articulable joint, a second electrode arranged at a second joint region of the sensor device that is configured to be positioned at the second articulable joint, and a reference electrode.
