Filed:

Jul 19, 2019

Appl. No.:

16/516777

Inventors:

- New York NY, US
Jonathan Reid - Brooklyn NY, US

Brandon Pool - New York NY, US

Assignee:

CTRL-labs Corporation - New York NY

International Classification:

A61B 5/0488
A61B 5/00

Abstract:

Arrangements for improving neuromuscular recording electrode contact with a body surface are described. According to some aspects, a sensor assembly may include a housing and one or more electrodes that are moveable relative to the housing. The electrodes may rotate and/or translate relative to the housing and/or have at least two degrees of freedom relative to the housing. The sensor may include a spring element that stores potential energy and biases the electrodes toward a starting position in which the electrodes extend at least partially out of the sensor housing. In some embodiments, application of a contact force to one or more of the electrodes of the sensor compresses the spring element, causing the spring element to store potential energy.

H05K 9/00
A61B 5/0488

Abstract:

Techniques for shielding wearable surface electromyography (sEMG) devices are described. According to some aspects, an sEMG device may comprise amplification circuitry comprising at least a first differential amplifier and at least two sEMG electrodes electrically connected to the amplification circuitry. The device may further comprise at least one auxiliary conductor not electrically connected to the amplification circuitry, wherein the at least one auxiliary conductor is configured to be electrically coupled to a wearer of the wearable device, and an electromagnetic shield surrounding the wearable device at least in part and electrically connected to the at least one auxiliary conductor.

Abstract:

Dual-supply analog circuitry for amplifying surface EMG (sEMG) signals is described. The circuitry includes a differential amplifier configured to be powered from dual-supply voltages. A positive input terminal of the differential amplifier is configured to be DC-coupled to a first sEMG electrode of a dry sEMG electrode pair and a negative input terminal of the differential amplifier is configured to be DC-coupled to a second sEMG electrode of the dry sEMG electrode pair.
