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 piezoelectric sensor that includes a piezoelectric film, first and second adhesive layers, first and second plate electrodes and a glass plate. The piezoelectric film includes first and second principal surfaces. The first adhesive layer attaches the first plate electrode to the first principal surface. The second adhesive layer attaches the second plate electrode to the second principal surface. The second plate electrode is attached to the glass plate such that the second adhesive layer and the second plate electrode are interposed between the piezoelectric film and the glass plate. The glass plate is distorted by being pushed. The second adhesive layer is thicker than the first adhesive layer.

摘要： A vibration structure that includes a film constructed to deform in a plane direction as voltage is applied thereto, a frame-shaped member, a vibration portion surrounded by the frame-shaped member in a plan view of the vibration structure, a support portion connecting the vibration portion and the frame-shaped member and supporting the vibration portion within the frame-shaped member, a first connection member that connects the film and the frame-shaped member, and a second connection member that connects the film to the vibration portion such that the vibration portion vibrates in the plane direction when the film is deformed in the plane direction. The support portion is disposed at a position closer to a center of gravity of the vibration portion than an end portion of the vibration portion when viewed in the plan view.

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.
