    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.

    摘要： A vending machine interface includes a front panel, a product selection panel, and a piezoelectric element. The front panel bends in a normal direction when being pushed by a user. The product selection panel is disposed facing the front panel. A detection element is attached to the product selection panel and configured to detect bending of the front panel.

    摘要： A housing includes a side wall that includes a button region that receives a pressing operation and a bottom wall that cooperates with the side wall to define a cavity. The bottom wall has first and second regions in which the first region is more easily displaced in response to the pressing operation than the second region. A press sensor is disposed on the bottom wall in the cavity and extends across portions of the first and second regions. A slit is located in the bottom wall between the side wall and the second region and causes the first region to be more easily displaced in response to the pressing operation than the second region.

    摘要： A monitoring system for determining whether an object is touched by a living body includes a receiver and a piezoelectric sensor attached to a substrate such that when the substrate is attached to the object. The piezoelectric sensor generates an output signal as a function of whether the living body is in contact with at least one of the substrate and the object. A processor processes the output signal to determine whether the living body is in contact with at least one of the substrate and the object and outputs a contact information signal containing information indicative of whether the living body is in contact with at least one of the substrate and object based on the determination. A transmitter transmits the contact information signal to the receiver.
