摘要： An electronic device with pressing input function has a substantially rectangular parallelepiped housing. In the housing, a pressing sensor, a display panel, a protection member, and a computation circuit module are arranged. In the display panel, a polarization plate is arranged on a first side of a liquid crystal panel. In the pressing sensor, electrodes are formed on both planar faces of a piezoelectric film having double refractivity. The pressing sensor is arranged on the operation surface (the display face) side of the housing relative to the front polarization plate.

摘要： An electronic device that includes a housing and a piezoelectric sensor. The piezoelectric sensor is disposed in contact with an inner wall surface of the housing while in a bent state. The piezoelectric sensor includes a piezoelectric film, a coverlay, a first electrode, a second electrode, a third electrode, and a substrate having flexibility. The first electrode is disposed on a surface of the substrate. The first electrode includes a wide part and a narrow part. The coverlay covers a boundary between the wide part and the narrow part. The piezoelectric film covers a boundary between a part of the first electrode which is covered with the coverlay and a part of the first electrode which is not covered with the coverlay.

摘要： A pressing force sensor that includes a sensor element configured with a piezoelectric film, a lead terminal for connection to an external circuit, a wiring conductor which connects pressing force detection electrodes and the lead terminal, and a flexible printed circuit board which withstands solder reflow temperatures. The flexible printed circuit board has the pressing force detection electrodes formed on a first principal surface thereof, and is folded via a folding line while the first principal surface faces inward. The sensor element is deflected by a pressing force applied to a second principal surface which faces outward and is in a first area of the flexible printed circuit board which is on one side with respect to the folding line, and a signal corresponding to the pressing force is thus taken out from the pressing force detection electrodes.

摘要： A device for detecting a holding state of an object. The device includes a housing for the object that has a shape that can be held by an operator and a piezoelectric sensor attached to the housing. Moreover, a detecting unit can detects a holding state of the housing by using a fluctuation amount of an output voltage of the piezoelectric sensor. The housing has a shape having a hollow space and the piezoelectric sensor has a flat film shape and is disposed in contact with an inner wall surface of the housing. The piezoelectric film produces charges when stretched and contracted in response to a displacement of the housing that are outputted as a voltage to the detecting unit. When detecting that the output voltage significantly fluctuates, the detecting unit identifies that the object is being held.
