Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201500582-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>A piezopotential‐powered active matrix strain sensor array</bold> based on a piezopotential‐gated graphene transistor (GT) is demonstrated using a piezoelectric polymer. The strain sensor based on the piezopotential‐gated GT exhibits excellent performance, including ultrahigh sensitivity (gauge factor = 389) and good durability (&gt;3000 bending and releasing cycles) with a minimum detectable strain at 0.008%. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgjrk4h2m9" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
