Abstract

The current technology push to connect everyday objects via the “internet of things” has fueled significant advances in low-power processing and communication devices. One aspect of these connected products that still needs attention is the means by which they are powered. An attractive and feasible option is the use of energy harvesting from acoustic fields. Previous work developing a piezoelectric energy harvesting device has generated 2.6 mW of power from a hydraulic test rig. This paper presents an implementation of an energy harvesting device connected to a communications system that allows it to store energy and communicate sensor readings via Bluetooth Low Energy.
