Dear all:

I am doing research on piezoresistive sensing issues, specipiclly, for
the mechanical mixer applications, but in my knowledge, up to date, the
piezoresistive approach is DC and for low frequency. But i am target at
20MHz, is that possible for piezoresistive sensing approach?

Anyone got some advice on that,or suggest some literature for me?

Thanks very much indeed.

TT
