Embodiment Construction

[0030]Construction of a laboratory test setup consisting of a surface electromyography (sEMG) sensor unit constructed of metal electrodes from Otto Bock's 13E125 device, mounted at original pitch and connected to an external preamplifier connected. Since force sensing resistors (FSR, forcesensing resistor) are flat and easy to use, three FSRs are used as force sensors. Three independent FSRs estimate the magnitude and location / direction of external forces that may be relevant for identifying unintended artifacts in the main signal. Figure 1 to Figure 3 The FSR sensor in our experimental setup is an off-the-shelf component, but smaller sensors can also be built so that the entire device fits in a prosthetic socket.

[0031] These sensors are sandwiched between two layers of acrylic glass ( figure 1 and figure 2 ). The electrodes are in contact with the structure, and the reference electrode is located at the center of the FSR array.

[0032] The device was strapped to th...

Abstract

Apparatus for measuring a bio-signal associated with contraction of a muscle in a human or animal body. The apparatus has a sensor for placement in contact with the body for measuring said muscle contraction signal. It also includes means for measuring a contact force and/or relative movement between the sensor and the body.

Description

technical field [0001] The present invention relates to the measurement of signals produced by biological entities to control artificial devices, in particular, but not limited to, to the control of prosthetics, orthotics or other devices via myoelectric, myacoustic or similar control interfaces. Background technique [0002] People who lose limbs are often given "prosthetics" or prostheses. The prosthesis may be completely passive and primarily cosmetic, but it may also be integrated with a mechanical joint that is driven by the user through a harness assembly. More commonly, there may be prostheses with mechanical joints driven by motors. An electronic control system controls these motors based on various control signals from the user. The latest technology for upper limb prostheses is controlled by electromyographic signals generated by active muscles, which are recorded by electrodes located on the surface of the skin to control the prosthesis. The magnitude of the EM...
