The STREAL semiconductor strain sensor was used in an equipment vibration monitoring demo exhibited at the Maxell Ltd. (hereinafter referred to as "Maxell") booth at the NEPCON Japan Electronics Development and Implementation Exhibition, held at Tokyo Big Sight from Wednesday, January​ ​24th​ ​to Friday, January 26th, 2024.

STREAL was used in an equipment monitoring demonstration, an example of an application that takes advantage of the characteristics of Maxell's all-solid-state batteries. At the exhibition venue, STREAL was attached to the equipment's compressor, electricity generated by energy harvesting was charged into the all-solid-state battery, and during measurements, electricity was supplied from the all-solid-state battery to STREAL for monitoring. The results of this demonstration experiment were made public. The operating status of actual machinery used at a Maxell group company was monitored at 30-second intervals for 40 days. As a result, vibrations during compressor and cylinder operation were detected and displayed as waveforms.

During this period, no trouble or wear requiring maintenance occurred, and normal waveforms could continue to be recorded. Further evaluations in the future will further demonstrate the effectiveness of Maxell's all-solid-state batteries and STREAL, which operates with low power consumption, for predictive maintenance of machinery.
Please look forward to Maxell's all-solid-state batteries and STREAL's efforts in the future.
