EMG Sensors - How does Athos do it

Other Hardware Sensors
1

Hi guys,

I'm working on a prototype athletic suit that incorporates EMG sensors amongst other things. I'm considering using the new (soon to be available) Myoware msucle sensor. (http://www.advancertechnologies.com/p/shop_3.html)

My questions is does anyone have an idea how Athos (https://www.liveathos.com/) puts so many sensors into their suits for the price? It says it has about 22 sensors.

The MyoWare sensor looks awesome but will only do one muscle per board. That wold make it about $800 to do the same number.

Any thoughts?

cheers!!

You could multiplex the MyoWare. You'd need to cut the trace from the on-board IA and use an off-board IA per channel to do this. The multiplex's output would be connected to the RAW pin on the MyoWare.

BTW Athos says on their website they measure 12 EMG locations on the shirt and 8 on the shorts which I believe have independent hardware units.

Hi!

Thanks for the info, very much appreciated!!

Have you done any work on this type of solution yet or would I be breaking new ground?

What do you think is the realistic number of muscles that could be monitored concurrently per myoware board with these type of upgrades?

Thanks again!!

cheers

Hey benq,

Were you able to prototype the Athos like suit eventually?
