Abstract: A sensor device includes a substrate; a piezoelectric film on the substrate; a lower electrode and an upper electrode that face each other with at least part of the piezoelectric film sandwiched therebetween; and a sensitive film in a region on the upper electrode that approximately corresponds to a resonance region, the resonance region being defined as a region in a plan view in which the lower electrode and the upper electrode face each other with the piezoelectric film sandwiched therebetween and in which a resonance in a thickness longitudinal vibration mode occurs, the sensitive film being absent in regions on the upper electrode and on the lower electrode that are outside of the resonance region in the plan view.

Abstract: An air conditioning system includes: an air conditioner to regulate a state of air in a room; a sensor device including at least one detector to detect an amount of an odor-causing substance included in the air in the room; and a control device to control operation of the air conditioner. The control device includes: a first acquisition unit to acquire a detected value of each of the at least one detector at a first timing when a person is present in the room; a second acquisition unit to acquire a detected value of each of the at least one detector at a second timing later than the first timing; a difference calculator to calculate a difference between the detected value at the first timing and the detected value at the second timing; and an instruction unit to control operation of the air conditioner based on the difference.

Abstract: A transmitting/receiving filter (filter device) according to one embodiment of the present invention is provided with a transmitting filter, a receiving filter, and a support substrate. The transmitting filter includes a first resonator constituted of a BAW device (FBAR, SMR). The receiving filter includes a second resonator constituted of a Lamb wave device. The support substrate supports both the transmitting filter and the receiving filter. The transmitting filter and the receiving filter are constituted of elastic wave resonators that resonate at different oscillation modes from each other, which allows miniaturization of the support substrate to be realized while preventing oscillation interference between the two filters.

Abstract: [Object] To provide an arithmetic device, an arithmetic method, and a gas detection system that are capable of easily correcting deterioration over time of a detection element.
[Solving Means] The arithmetic device includes a calculation unit. The calculation unit calculates a correction coefficient from a detection element that causes a resonant frequency change by adsorption of gas on the basis of a resonant frequency change amount associated with a humidity change of the detection element in a degraded state and a resonant frequency change amount associated with a humidity change of the detection element in an initial state that was acquired in advance, and corrects the resonant frequency change amount of the detection element in the degraded state by using the correction coefficient.

Abstract: A gas determination method uses a sensor having a field-effect transistor structure including a gate electrode, an insulating film formed on the gate electrode, a source electrode and a drain electrode formed on the insulating film, and a graphene layer formed on the insulating film and connecting the source electrode and the drain electrode to each other. The gas determination method includes: supplying gas to the graphene layer; applying a first voltage to the gate electrode for a predetermined period of time; and thereafter measuring a change in a current flowing between the source electrode and the drain electrode when a sweep voltage is applied to the gate electrode, repeating the same current measurement with a second voltage different from the first voltage, and determining the gas based on the measurement results.
