Hi
I am driving a piezolelectric element (ceramic) at alternating voltage between 10V and 20V at a frequency of 8hz. The piezo is attached to my skin. Meanwhile I am recording Electromyography from my skin to capture the effects of the piezo on my muscles. However the 8hz alternating driving voltage is being picked up and want to get rid of it. How do I shield from this artifact?
Thank you
Rani
