Abstract: A sensing system includes an electronic tag and a reading device that transmits and receives information to and from the electronic tag. The reading device includes a transmission unit that sends an alternating-current radio wave including a high-frequency component and a low-frequency component. The electronic tag does not include a power supply and includes a receiving unit that obtains a power supply voltage from the high-frequency component of the alternating-current radio wave and obtains a clock signal from the low-frequency component and a return unit that maintains a maximum amplitude of the clock signal and sends a combination of information and the clock signal as a return signal. The reading device further includes a processing unit that decodes the return signal sent from the electronic tag on the basis of the clock signal.

Abstract: An information collection system includes a plurality of radio tags and a reading device. Each of the radio tags stores identification information and includes a sensor, an antenna that receives a carrier wave from the reading device, and a data transmission unit that sends measurement data including the identification information and information obtained by the sensor to the reading device after the carrier wave is received by the antenna. The plurality of radio tags send the identification information and the information obtained by the sensor with different natural periods from the data transmission units. The reading device transmits the carrier wave to each of the radio tags, receives data from each of the radio tags, and obtains the data.

Abstract: An organic semiconductor element functions as a strain sensor, and includes a substrate and an organic semiconductor layer formed on the substrate as a single-crystal thin film of an organic semiconductor that is a polycyclic aromatic compound with four or more rings or a polycyclic compound with four or more rings including one or a plurality of unsaturated five-membered heterocyclic compounds and a plurality of benzene rings. Since the organic semiconductor layer is formed as the single-crystal thin film, an identical crystal structure is obtained regardless of formation technique. Therefore, when the same strain is given, the same carrier mobility is obtained and uniform property is obtained with respect to the strain. Accordingly, it is possible to provide strain sensors having uniform property.
