Abstract: A pressure sensor detects a pressure of a pressure transmitting medium. The pressure sensor includes a sensor substrate and a protection film. The sensor substrate includes a recess recessed relative to a periphery thereof and a thin portion thinner than the periphery due to the recess. The protection film is provided on a bottom surface of the recess that is one side of the thin portion and a part of a lateral surface of the recess, and the protection film suppresses an adhesion of a contamination contained in the pressure transmitting medium. The pressure sensor includes an adhesion suppressing portion that includes an uneven section formed in at least a part of the lateral surface, and a liquid repellent film repellent to liquid in the pressure transmitting medium and provided as the protection film on the uneven section to exhibit a lotus effect.

Abstract: A battery monitoring device monitors a battery that is rechargeable and dischargeable. The battery monitoring device includes a factor monitoring unit that monitors a factor that leads to an abnormal heat generation phenomenon in which a temperature of the battery continues to rise unintentionally, and an abnormality detection unit that detects an abnormality in the battery. The abnormality detection unit reduces occurrence of the abnormal heat generation phenomenon in advance based on a monitoring result of the factor, and detects an abnormal state occurring in the battery at an initial stage of the occurrence of the abnormal heat generation phenomenon to implement a countermeasure against the abnormal heat generation phenomenon based on a detection result of the abnormal state.

Abstract: A battery monitoring device monitors a lithium precipitation amount in a lithium ion battery. The battery monitoring device includes a precipitation amount detection unit that has a short circuit for discharging the lithium ion battery by temporarily shorting both ends of the lithium ion battery. The lithium precipitation amount detection unit calculates an estimation value of the lithium precipitation amount based on a change in at least one of current or voltage when both the ends of the lithium ion battery is shorted by the short circuit. The battery monitoring device includes a temperature sensor that detects a battery temperature of the lithium ion battery.

Abstract: A battery monitoring system includes a monitoring unit that monitors a battery and a higher device that is provided with monitoring data obtained by monitoring of the battery by the monitoring unit and saves, by using a blockchain, at least part of specific information included in the monitoring data. The higher device includes a block generation unit that generates a new block including a hash value based on the at least part of the specific information and a last block linked at an end of the blockchain, and an external communication device configured to save, in a distributed manner in a plurality of external devices, the new block generated by the block generation unit. At least one of the monitoring unit or the higher device is provided with a data protection unit configured to ensure reliability of the monitoring data.

Abstract: In a facility state monitoring system, a sensor node includes a sensor that outputs, as sensor data, data indicating the state of a facility as a monitoring target, a communication unit, and a power supply unit that supplies power to the sensor and the communication unit. The sensor node is commonly used by multiple monitoring targets. A receiver receives the sensor data transmitted from the communication unit. A state detection unit receives the sensor data received by the receiver, and learns, as learning data, normal states of the monitoring targets based on normal sensor data corresponding to normal operations of the monitoring targets. In response to the receiver receiving the sensor data transmitted from the sensor node after learning, the state detection unit compares states of the monitoring targets indicated by the sensor data with the learning data to detect an abnormality occurrence or symptom in the monitoring targets.
