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. date: 2019-06-07 date_type: published publisher: IEEE official_url: http://doi.org/10.1109/MCE.2019.2892264 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1523759 doi: 10.1109/MCE.2019.2892264 lyricists_name: Gao, Shuo lyricists_name: Wu, Linxiao lyricists_id: SGAOX49 lyricists_id: LWUXX09 actors_name: Gao, Shuo actors_id: SGAOX49 actors_role: owner full_text_status: public publication: IEEE Consumer Electronics Magazine volume: 8 number: 4 pagerange: 28-31 issn: 2162-2248 citation: Gao, S; Wu, L; (2019) Why Piezoelectric Based Force Sensing is not Successful in Interactive Displays?
