ESG-Link energy-harvesting wireless strain sensor modules operate indefinitely — without the need for batteries — by converting cyclic strains into dc power using piezoelectric materials.
The modules feature a precision timekeeper, nonvolatile memory for onboard data logging, and a frequency-agile IEEE 802.15.4 transceiver. Sampling rates, sample durations, sensor offsets, sensor gains and onboard shunt calibration are wirelessly programmable.
