按压检测传感器
Abstract:
按压检测传感器(1)具备操作受理部件(20)、压电传感器(10)。操作受理部件(20)是玻璃盖(21)、触摸传感器(22)、显示面板(23)分别经由粘着剂(231、232)而被固定的层叠刚体板。压电传感器(10)具备压电性薄膜(11)，在该压电性薄膜(11)的操作受理部件(20)侧的面具备第一检测部件(12)，在与操作受理部件(20)相反的一侧的面具备第二检测部件(13)。第一检测部件(12)被粘合部件(30)粘合于操作受理部件(20)，并且被粘着剂(141)粘合于压电性薄膜(11)。高温时，操作受理部件(20)的挠曲相对地变大，但粘着剂(141)的弹性模量降低。低温时，操作受理部件(20)的挠曲相对地变小，但粘着剂(141)的弹性模量不降低。
Abstract(English):

A press detecting sensor that includes an operation receiving member and a piezoelectric sensor. The operation receiving member is a multilayer rigid plate including a cover glass, a touch sensor and a display panel fixed via first bonding agents. The piezoelectric sensor includes a piezoelectric film, a first detecting member on a surface at a side of the operation receiving member of the piezoelectric film, and a second detecting member on a surface at a side opposite to the operation receiving member. The first detecting member is bonded to the operation receiving member by an adhesive member, and is bonded to the piezoelectric film by a second bonding agent.
