WIRELESS ELECTROMYOGRAPH RECORDER

Muscles generate low voltages which are around 100 mV when they contract. These
voltages are weakened by internal tissues and the skin. Even though the voltages are
weak but they can be measurable at the surfuce of the skin. Electromyography (EMG)
recorder is used to measure a muscle electrical activity that occurs during muscle
contraction and relaxation cycles. In medical applications, people mostly used a wired
EMG recorder. However, the advanced technology had allowed wireless collection and
recording of muscle electrical activities using an EMG recorder. Thus this report is
going to discuss in depth about a wireless EMG recorder. This project background study
will include problem statements to justifY the need of this project, objectives, scope and
limitation of the project as well as project feasibility. Literature reviews will also cover
aspects like EMG signal, conventional EMG recorder, and types of wireless network
that can be used. In the methodology part, the proposed design, tool and equipment will
be discussed further. Result and discussion will explain about the output obtained from
the project. This report will be wrapped up with a conclusion.
