Abstract: A disposable, low profile sensor overlay covering for use with biomedical sensors and which includes a framework of flexible component layers supporting an arrangement of electrostatic shielding, insulating, cushioning, and electrically conductive adhesive substrate components configured to form a protective covering encasing the sensor. The combination of component layers provides a means to stabilize the relative position of the sensor with respect to the skin and reduce the potential for sensor dislodgment. The mechanical and electrical configurations act in synergy to shield the sensor from external electrical fields and suppress movement artifact.

Abstract: A disposable, low profile biomedical sensor for detecting electrical signals from muscles and which consists of a framework of malleable and flexible component layers supporting an arrangement of conductor leads embedded within electrically conductive, adhesive, cross-linked hydrophilic polymer gel components configured to form signal detection and reference electrode contacts. The combination of component layers provides a sensor and lead cable that is flexible and can be contoured to conform to the underlying musculature. The mechanical and electrical configurations act in synergy to shield the sensor and lead cable from external electrical fields and suppress movement artifact.

Abstract: A sensor system for detecting and processing EMG signals including a substrate having a bottom surface adapted for attachment to skin; a plurality of spaced apart electrode arrays projecting from the bottom surface so as to engage the skin and detect EMG signals in muscles located under the substrate; and four differential amplifiers connected to receive EMG signals from four distinct pairs of electrode arrays. The electrode arrays detect the action potentials of the muscle fibers from various orientations so that the shape of an action potential appears substantially dissimilar in each of the four differential pairs.

Abstract: A muscle function analysis system including a base; a restraint device supported by the base and shaped and arranged to receive and immobilize a human body portion retaining a muscle group concurrently activatable to produce a body function; and a support apparatus supported by the base and shaped and arranged to support other portions of the body, the support apparatus adapted to substantially isolate activity in the muscle group from muscle activity in the other body portions. Also included are an electrode array adapted for coupling to the muscle group so as to receive myoelectric signals generated by muscle activity therein and a processing system coupled to the electrode array and adapted to process the myoelectric signals. By isolating muscle activity in a particular muscle group, more useful data is obtained for evaluating muscle dysfunction in the group.

Abstract: A device and a method for anatomic implantation to provide electrical interface to nerves. Included in the device are a pair of electrical leads secured to a coupling formed from a piece of woven sheet material, and having ends connected to spaced apart input terminals disposed adjacent to an inner surface of the coupling. Connected to the opposite ends of the leads are output terminals for interfacing to electrical recording or measuring instruments. During implantation, a subject nerve is embraced by the inner surface of the sheet material which is shaped for juxtaposition the outer surface of the nerve at a minimum spacing therefrom of 0.3 millimeters. In the period following implantation the interstices of the sheet material coupling receive anatomic tissue growth establishing a structurally stable dimensional relationship between the nerve and both the input electrodes and the coupling.
