    摘要: Disclosed herein is a stress sensor that includes a stress detection layer including a laminated body including a first ferromagnetic layer, a first non-magnetic layer, a second ferromagnetic layer, and an antiferromagnetic layer stacked one on another. The antiferromagnetic layer includes Mn, and the magnetization direction of the second ferromagnetic layer is fixed by the exchange bias caused by the exchange coupling with the antiferromagnetic layer. The stress sensor detects a stress by an electric resistance depending upon a relative angle between magnetization directions of the first ferromagnetic layer and the second ferromagnetic layer, the relative angle changing depending upon an externally applied stress.

    摘要: A composite capacitor that includes a first capacitor and a second capacitor. Each of plural first columnar conductors and each of plural second columnar conductors have a nano-size outer diameter. The composite capacitor includes a connecting conductor layer and a reinforcement conductor. The reinforcement conductor is located between a first counter electrode layer and a second counter electrode layer of the first capacitor and the second capacitor, respectively, and is connected to each of the first counter electrode layer, the second counter electrode layer, and the connecting conductor layer. The material forming the reinforcement conductor is the same as each of the first counter electrode layer and the second counter electrode layer and is different from the material forming the connecting conductor layer.

    摘要: An RFID tag is provided that transmits and receives a communication signal. The RFID tag includes a base material, an antenna pattern provided on the base material, and an expansion member. The expansion member is disposed adjacent to the antenna pattern and has a coefficient of linear expansion that is higher than coefficients of linear expansion of the antenna pattern. When the RFID tag is subjected to an electromagnetic wave heating microwave, and thus the temperature of each portion rises, the antenna pattern breaks at a position of the expansion member. With this configuration, ignition and combustion are able to be prevented even in a situation in which the RFID tag is subjected to high-frequency power for heating a food item while being attached to the food item.

    摘要: An electronic device is provided in which a capacitance of a capacitor that is formed between one or more reference second touch sensor electrodes and at least one first touch sensor electrodes is defined as a first reference capacitance with the capacitor formed when the touch sensor is folded along a folding line. Moreover, a capacitance of a capacitor formed between a left second touch sensor electrode and at least one of the plurality of first touch sensor electrodes is defined as a left capacitance. Furthermore, a capacitance of a capacitor formed between a right second touch sensor electrode and at least one of the plurality of first touch sensor electrodes is defined as a right capacitance. Using these capacitances, a determining unit of the electronic device can determine that a touch sensor is folded if both the left and the right capacitances are greater than the first reference capacitance.
