Disposable low-profile conformable biomedical sensor
First Claim
1. A biomedical sensor that provides an electrode to body interface, comprising:
- a plurality of individual electrically conductive, adhesive, cross-linked hydrophilic polymer gel substrate layers which form a plurality of signal detection electrode contacts and an elongated electrically conductive polymer reference electrode contact;
a plurality of insulated conductor leads electrically connected to the electrode contacts and extending away from the electrode contacts, the leads being embedded and fully enveloped lengthwise within the elongated electrically conductive hydrophilic polymer reference electrode contact to form a lead cable shielding the sensor and leads from external electrical fields and suppressing movement artifact while providing a conformable, contoured attachment of the sensor and lead cable to underlying skin of the body; and
a conformable framework mechanically supporting and electrostatically shielding the insulated conductor leads and electrode contacts.

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.
