The idea was to take a very sensitive commercially available planar sensor = and compare to a new sensor material under development. I guess we're looki= ng for accuracy & reputability. I've never tried piezos for this, though I was aware they could be used for= force sensing. I have no feeling if one could be calibrated to do what I w= ant. detecting spikes as a result of a 'hit' is OK as long as the amplitude= scales with the force of the strike. Ideally I'd be wanting a commercial sensor tough.

Subject: Re: [EE:] Looking for thin ( & sensitive) force sensors Can you use a generic/junkbox piezo element? They won't do a constant output as in 'dc', but they do produce spikes. Not sure how much accuracy/repeatability you need. On 10/14/2016 11:31 AM, Joe McCauley wrote: > I'm looking for some planar sensitive force sensors that I can stick onto= a flat surface.
