Amplifying the Body's Electric Signals with SEMG

- While at the Disrupt Hackathon in May, Bil work with a couple of people from the Hackaday Community who were developing hardware to react to the electrical signals generated when moving the muscles in your body.
This Surface ElectroMyography (SEMG) presents an interesting problem. The signals themselves are quite small and the environment for measuring them is noisy. The method Bil used is to feed the raw signals into an Instrumentation Amplifier and then use filters and OpAmps to condition the resulting signal.

amazing work bill! as a student when all the theory gets tiring its so motivating and amazing to see the applications of what im studying! thanks a bunch!
Great work and video，Marked!
Great video!
Nice video! Could it be possible you made something related to a DIY ECG/EKG? I'd love to make one of these!
slendertone ab belts have gel pads that also wear out. however, if you apply hand sanitizer to them you can revitalize them so that they last longer.
try adding hand sanitizer to your pads and see if that helps.
Bill, you mentioned Mr. David Niam link in your video, who has a project up in a Hackaday IO about Surface EMG...Can you please share us the Link to the Viewers?
Thanks,
Rajiv.
Why is your filter set to 130 to 1300 Hz? Neural activity is frequency modulated and very strong stimulus generates frequencies of 200 to 300 Hz maximum. Where did this filter range come from? Also, what power supply are you using? The schematic referred to on another web page doesn't show anything.
hello, i tore my aorta of my heart, the docs operated on me for 5 hrs leaving me incomplete paraplegia,when i left hospital i was pretty much not feeling from the nipples down, 10 years later i can feel my legs and move quite a bit anyway i have been thinking about making my signals from my brain stronger, when i swim i can now do the breaststroke action, i was thinking about getting gold dust tattooed down my back from lower neck, the messages are just getting stopped but they are slowly getting to ground,,,,what do you think do you think this or something like this kick me up a bit :) im a bit mad and always watching mechanical and crazy stuff on you tube cheers Bill hackaday
Hey Bill , Cool stuff . Can you give some more info on the magnitude of the current . I guess its in the magnitude of nA . I want to explore energy harvesting .May sound silly !!
Hello Bill Sir I want help, from you to make this Device
Physician and neuro-muscular specialist Dr Edmund Jacobson who devised the Progressive Muscular Relaxation Technique and developed many of the ideas behind Bio-feedback, would have loved your compact circuit driving the small bargraph display. Unfortunately he was born in the 19th century and was way before his time. He had to make do with galvanometers to teach his subjects stress-reduction strategies in his lab. Your compact device could help stressed-out politicians and CEOs recently named in the Panama Papers learn how to relax and think more clearly about where to put their squillions of dollars. If marketed cleverly, perhaps it could be a great source of income 😉
COOL TO INTERPRETATE MEMORIAL SIGNS AND ELECTRICAL INFORMATION OF THE BRAIN. (mi ingles es un poco malo ,perdon por eso)
Nice idea to be improved upon - thanks for that. Contrarily and just for future reference, chances are pretty good that someone interested in making this circuit does NOT need some condescending crash course on the function of a capacitor!
This is how accidents happen... a Frickinstein just waiting to be born and say something weird and prove it's real.
