Abstract
The radioisotope actuated electro-mechanical power generators (REMPG) presented in the previous chapter convert radioisotope emitted kinetic energy to stored electromechanical energy using radioisotope actuation of piezoelectric unimorph cantilevers. The stored electromechanical energy is efficiently integrated over a reciprocation period, and discharged to generate pulsed electrical power through the piezoelectric with energy conversion efficiencies as high as 3.97%. The corresponding radioisotope kinetic to electromechanical energy conversion and electromechanical to electrical energy conversion efficiencies are ≈ 4.6% and ≈ 85% respectively.
