Title: Matthijs P Smits: Innovator in Myoelectric Technology

Introduction

Matthijs P Smits is a notable inventor based in Brookline, MA (US). He has made significant contributions to the field of myoelectric technology, holding a total of 4 patents. His work focuses on developing methods and apparatuses that enhance the functionality of prosthetic devices.

Latest Patents

One of his latest patents is a "Method and apparatus for detecting myoelectric activity from the surface." This innovative apparatus includes an electrode pair, processing circuitry, and up to three output leads. The signals detected at the electrode contacts are differentiated, amplified, and filtered. The filtered signals serve as a first input signal to a switch, while a ground signal acts as a second input. The amplified, unfiltered signals are tested against a preset threshold to determine their quality. If the signals exceed the threshold, they are deemed to have significant noise, prompting the switch to output the ground signal. Otherwise, the filtered signals are provided as the output. This apparatus can be integrated into prosthetic devices or used for testing with multiple electrode pairs.

Another significant patent is the "Prosthetics electrode array diagnostic system." This apparatus is designed for testing a muscle of a patient fitted with a myoelectric prosthetic device. It features an array of electrodes that test the muscle over a wide area in a short time frame. The electric signals from muscle contractions are amplified, filtered, and converted into digital signals. These digital signals are then sent to a computer, which displays the results for analysis. A prosthetist can utilize this information to optimize electrode placement in the device.
