This $230,583 National Science Foundation project grant supports the development of bio-inspired bistable energy harvesting technology for fish telemetry tags. Funded under the NSF Engineering program (CFDA 47.041), the award supports research collaboration between the University of Michigan and industry partners to design a novel attachment mechanism and self-powered sensing system for fish tags. The project aims to investigate snap-through dynamics of a piezoelectric energy harvester inspired by the Venus flytrap to power acoustic transmitters on tags. Researchers will also study the remora-shark relationship to guide design of a bio-inspired suction disc attachment with metal spikes, mimicking spinules. Work will include fluid-structure-piezoelectric interaction modeling, harvester dynamics modeling under complex excitations, and experimental validation on robotic and live fish to evaluate performance and impact on fish life and mobility. An education and outreach plan incorporates opportunities for undergraduates, K-12 students, and underrepresented groups.
