Abstract
A kinesthetic sensor measure angular displacement of body parts of users by measuring a density of substances contained in a conduit of the kinesthetic sensor. For example, the kinesthetic sensor measures the density of substance including in a conduit by transmitting a signal into the conduit and measuring the signal after the signal passes through the conduit and one or more substances included in the conduit. Based on the density of the one or more substances included in the conduit from the measured signal, an angular displacement of a user's body part proximate to the kinesthetic sensor is determined. Kinesthetic sensors may use different architectures such as an open-loop, a closed-loop architecture, or an architecture using blood vessels as conduits. Additionally, kinesthetic sensors can be flexible to conform to physical contours of different body parts.
