    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: An electronic device for long-term adhesion to a mammal includes a housing with an electronic component. The electronic device may include a first wing and a second wing, each being integrally formed with the housing. An electrode is positioned on a bottom surface of each of the wings, the electrodes electrically connected to the electronic component. An adhesive layer is provided for adhesion to a surface of the mammal. The adhesive layer may cover a portion of the bottom surfaces of the wings but generally does not cover the electrode or a bottom surface of the housing. A method of applying an electronic device to a mammal includes removing first and second adhesive covers from first and second wings of the electronic device to expose an electrode and an adhesive coated on a bottom surface of each wing.

  • Publication number: 20120310069
    Abstract: The system for displaying muscle force data includes a wearable patch and a remote visual display. The wearable patch carries electrodes suitable for sensing electromyographic signals on the skin of the patient. The patch carries circuitry which converts the detected electromyographic signal to a digital output which can be transmitted to the remote visual display. The circuitry relies on filtering to produce a usable digital signal at very low power consumption. The transmitted signal can be used to drive a variety of visual displays, including a conventional hand-held personal communicators and entertainment devices which had been programmed to suitably process the visual display.

  • Publication number: 20120302860
    Abstract: According to at least one example, an ambulatory medical device is provided. The device includes a plurality of electrodes disposed at spaced apart positions about a patient's body and a control unit. The control unit includes a sensor interface, a memory and a processor. The sensor interface is coupled to the plurality of electrodes and configured to receive a first ECG signal from a first pairing of the plurality of electrodes and to receive a second ECG signal from a second pairing of the plurality of electrodes. The memory stores information indicating a preferred pairing, the preferred pairing being either the first pairing or the second pairing. The processor is coupled to the sensor interface and the memory and is configured to resolve conflicts between interpretations of first ECG signal and the second ECG signal in favor of the preferred pairing.
