Electromyograph data acquisition and application using Cypress Programmable System on Chip

摘要

This project touches upon a number of research domains such as embedded systems, VLSI, signal processing and control systems. We have a made use of the special features of Cypress PSoC 5LP such as excellent analog precision, flexible architecture and programmable IDE to design our own EMG data acquisition system at the hardware level. The purpose of this project is to acquire data for EMG activity which has scope to be implemented in actuating prosthetic robotic arms, exoskeletons and other biomedical applications. Generally, filters and rectifiers are designed with opamps and discrete components but PSoCs unique configurable and programmable analog peripherals allow the construction of intermediate stages using minimal external components. As each persons EMG activity is relatively different, PSoCs flexible IDE facilitates designing special application based models for individual requirements, thereby reducing cost and improving efficiency.
