Abstract: A device for recording movement and/or posture in a continuous area comprising an elastic therapeutic tape substrate for application to a body part, the tape substrate comprising an elastic two dimensional conductor along which an electrical current can flow to produce deformation data comprising change in resistance and/or capacitance as the elastic two dimensional conductor changes geometry in response to movement is described. The device may further comprise a data collection unit which receives the deformation data. Also described are a method and system for recording movement and/or posture in a continuous area comprising applying the elastic therapeutic tape substrate to a body part and producing deformation data comprising change in resistance and/or capacitance as the elastic two dimensional conductor changes geometry in response to movement to thereby record the movement in the continuous area.
