With　the　development　of　electronic　technology,　wearable　electronic　products　and　electronic　skin　have　become　the　emerging　products　in　this　world.　In　this　study,　two　kinds　of　flexible　plate　capacitors　were　prepared　by　an　optimized　spraying　process,　whose　electrode　layers　and　dielectric　layers　were　conductive　silicon　rubber　and　pure　PDMS,　respectively.　The　inner　surface　structure　of　the　capacitors　was　fabricated　with　the　aids　of　fabric　backup.　Initial　capacitance　and　capacitance　response　of　sensors　with/without　fabric　surface　structure　were　calculated　and　analyzed　according　to　formulae　of　equivalent　dielectric　constant　of　composite　dielectric　layers　and　equivalent　capacitance　of　the　capacitor.　Capacitance　responses　of　the　sensors　to　compressive　pressure　and　tensile　strain　loads　were　further　tested.　In　addition,　the　effect　of　spraying　parameters,　including　spraying　distance,　plate　area　and　resistance　of　the　CSR　with　loads　were　evaluated　on　the　response.　The　sprayed　flexible　capacitors　were　finally　demonstrated　its　potential　application　in　sensing　field,　such　as　water　dropping,　feet　lifting　and　walking.　Results　indicate　that　the　surface　fabric　structure　of　flexible　sensors　will　improve　its　stability　and　sensitivity,　which　assure　the　sensors　of　a　prospect　of　motion　sensor.　(C)　2019　Elsevier　B.V.　All　rights　reserved.
