Powering tiny machines in harsh environments – like sensors buried in ice or embedded in engines – is a global challenge. Micro-Electro-Mechanical Systems (MEMS) need long-lasting, maintenance-free energy, but traditional batteries simply fall short. Isotope batteries, which harness the energy of decaying atoms, offer a powerful alternative, if their low efficiency and power density can be overcome.
Supported by the Marie Skłodowska-Curie Actions programme, the BetaBatt project is rising to that challenge. By combining advanced materials, innovative battery structures, and cutting-edge simulations, it will build tritium-based micro-batteries that last over a decade and deliver reliable energy, even in extreme conditions. With this work, BetaBatt could unlock a clean, efficient future for micro-energy in Europe.
