C12890 EMG Electrode Placement within Prosthetic Limb Liner
Invention Novelty: A novel method of integrating the electromyogram (EMG) electrodes within the liner of the prosthetic limb to ascertain the user’s intention and improve flexibility of the prosthetic device.
Value Proposition: There are an estimated 1.9 million amputees in the US, with over 180,000 amputations performed each year. The rate of amputations increases substantially in patients over 65 years, and with the increasingly aging population, the number of amputees in the US will increase. The introduction of a larger number of electrodes increases the ability to ascertain the user’s intention and flexibility of the prosthetic device. This technology affords the ability to customize the placement of the electrodes and the signal processing unit to suit the shape of the individual’s residual limb, and the location of the prosthetic. The advantages of this technology include:
- The electrodes can be placed within the prosthetic liner, or in an arm band configuration
- The electrodes can be used in prosthetics placed in various locations across the body
- The signal processing systems can be easily replaced, should they falter
Technical Details: Johns Hopkins researchers have developed a novel system that integrates EMG electrodes into the prosthetic liner of the prosthesis. This placement allows the ability to integrate more sensors into the prosthesis, and places them close to the source of the EMG signals in the residual limb. A number of electrode types can be used, such as monopolar or bipolar electrodes, metallic or non-metallic electrode configurations. The placement of the electrodes can also vary along the length of the prosthetic.
Looking for Partners: To develop and commercialize the technology as improved electronic limb prosthesis with increased degrees of freedom.
