| Outline of Final Research Achievements |
An implantable power generation system driven by muscle contractions for supplying power to active implantable medical devices (AIMDs), such as pacemakers and neurostimulators, is proposed. In this system, a muscle is intentionally contracted by an electrical stimulation in accordance with the demands of the AIMD for electrical power. In this study, using the gastrocnemius muscle of a toad, the characteristics of muscle contraction by electricity stimulation was surveyed. Furthermore, micro rotary and linear type generators converting the muscle motion to electric power were proposed and tested.
