The second plate includes a conductive-resistant matrix layer and a plurality of conductive paths spaced apart throughout the matrix layer. The plurality of conductive paths are oriented perpendicular to a plane through which second plate extends. A plurality of electrodes is formed on, and spaced apart across, a first portion of the matrix layer with each electrode electrically coupled to at least one of the respective conductive paths. The electrodes are to receive charges from an external charge applicator to produce an electric field within the passageway to cause electrowetting movement of the liquid droplet.

A bicep muscle electromyographic (EMG) value is received from a bicep muscle EMG sensor and a tricep muscle EMG value is received from a tricep muscle EMG sensor. An intended flexion or extension angle of a forearm relative to an upper arm is calculated based on the bicep and tricep muscle EMG values. An arm avatar is rendered according to the intended flexion or extension angle of the forearm.
