N2  - Piezoelectric based force sensing in interactive displays attracts worldwide attentions due to its intrinsic ability in
efficiently converting mechanical energy to electric energy. However, commercialized piezoelectric based products
have not been successfully occupying the market, mainly
because of the unpleasant detection accuracy. To explain
this phenomenon to readers, in this article, we investigate
it through finite element analysis. The results reveal that
the instable force-voltage responsivity and propagated
stress from adjacent force touch locations are two key
issues that strongly degrade detection accuracy.
