Electromyography and You

Electromyography dates back a couple centuries to when a physician named Francesco Redi was studying the Electric Eel and discovered that electricity (a spark) was generated when the eel used specific muscles. Over the years following that scientists learn more and more about the connection between muscles and electricity, until 1890 when a french scientist named Marey coined the term electromyography.

There are two different types of electromyography on that is on the surface and one that is directly measure from in the muscle. We don’t want to be jabbing people with needles in our group so we will be focusing on surface electromyography (sEMG).

Over the past decade, EMG’s have played an integrate role in the medical field, specifically for neuromuscular conditional that include issues with motor control.

As it goes with some other technologies that we have worked with (brainwave reading), the availablity and interest of open hardware components has led to a wider range of uses for sEMG. In the new year there will be an armband available that has integrated surface electrodes and will be used to control many things with the move of a muscle.

Electromyographical sensors were selected for our upcoming project, and we are going to tied them into and Arduino which will process the muscle’s electrical activity and allow us to code in an appropriate response. Below are some links to the ones that we have selected to test out to see what can be done and if we will need to build out own in the end.
