In a first region, a multilayer body is bent along a first bending line such that a first main surface is located farther on an outer peripheral side than a second main surface. In a second region, the multilayer body is bent along a second bending line such that the first main surface is located farther on an inner peripheral side than the second main surface. In the first region, a first metal foil layer is located farther on an outer peripheral side than a center of the multilayer body. In the second region, a second metal foil layer is located farther on the outer peripheral side than the center of the multilayer body. In the second region, a distance between the second metal foil layer and the second main surface is shorter than a distance between the second metal foil layer and the first main surface.

Multilayer substrate and electronic device

A flexible board includes a flexible resin base material, a conductor pattern on a principal surface of the resin base material and including first and second electrodes electrically separated from each other, a first protective film having lower flexibility than the resin base material and covering a portion of the conductor pattern, and a second protective film having higher flexibility than the first protective film and extending over the principal surface of the resin base material and the first protective film to cover another portion of the conductor pattern. The first protective film is closer to the first and second electrodes on the principal surface of the resin base material than the second protective film. The first protective film includes a first opening exposing a portion of the first electrode and a second opening exposing a portion of the second electrode in planar view.

Flexible board, method for manufacturing the same, and electronic device

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.

Monitoring system

A pressing sensor is provided that includes a first sensor element that outputs a voltage corresponding to an amount of displacement in shape of a receiving unit that receives a press operation; a press operation determining unit that determines whether the receiving unit is in a state of receiving a press operation; and a setting unit that, after elapse of a first prescribed time from a point of time at which the press operation determining unit determines that the receiving unit has received a press operation, sets an absolute value of a threshold that is smaller than an absolute value of the threshold before elapse of the first prescribed time, the absolute value of the threshold representing a difference from a ground voltage value for determining whether the receiving unit has ended reception of the press operation.

Pressing sensor and electronic device for detecting the end of a press without error

Disclosed is a piezoelectric film sensor including an insulating substrate having a first electrode formed on at least one main surface thereof, a piezoelectric film which has a first main surface and a second main surface and in which the first main surface is provided on the first electrode side, and a conductive thin film member provided on the second main surface side. The piezoelectric film sensor is characterized in that the first main surface is disposed on a pressing surface side.

Piezoelectric film sensor and holding state detecting device

An operation input device having an exterior portion that includes a band portion extending in a belt shape and having flexibility and a housing; and a control unit () that is housed in the exterior portion and performs input processing based on a detection signal indicating detection of a predetermined operation. The operation input device is provided with a deformation detection unit that outputs a detection signal associated with a deformation of the band portion or a deformation of the housing to the control unit.
