Abstract: A system for muscle activity sensing and feedback includes a base textile, an electrode coupled to the base textile, a sensor coupled to the base textile, a controller coupled to the base textile, and a feedback element coupled to the base textile. The feedback element is in communication with the controller. The feedback element receives a feedback signal from the controller and imparts feedback to a user based on an electrical signal from the electrode and/or a sensor signal from the sensor.

Abstract: A blunt force sensor array for application to a non-planar surface includes a flexible thin-film substrate, a plurality of force sensors secured to the flexible thin-film substrate proximate to a center measurement point, a strain gauge secured on the flexible thin-film substrate proximate to the center measurement point, and a sensor interface configured to connect to external measurement and control circuitry. The sensor interface may be electrically connected to each of the force sensors and the strain gauge via traces disposed on the flexible thin-film substrate. The flexibility and shape of the flexible thin-film substrate may permit the blunt force sensor array to be applied to the non-planar surface to detect forces and strains experienced by the non-planar surface in response to a blunt force event on the non-planar surface.
