Pacific Northwest National Laboratory (PNNL) seeks to solve the problem of short-lived batteries in fish tags by replacing the battery with a piezoelectric-based EH unit that harvests the biomechanical energy of the host animal’s motion. The goal is to prepare this self-powered transmitter for commercialization by demonstrating its viability and market impact in collaboration with private partners to enable longer term montioring of fish. PNNL will increase the technology readiness level (TRL) to 8 for white sturgeon research and monitoring by conducting developmental testing and evaluation of the system in actual field environments.
