Achieving low power in nanotechnology involves several strategies: 1. Material Innovation: Utilizing materials like graphene and carbon nanotubes that have superior electrical properties. 2. Device Architecture: Designing efficient transistor architectures, such as FinFETs and Tunnel FETs, which are more power-efficient than traditional MOSFETs. 3. Energy Harvesting: Incorporating techniques like piezoelectric and thermoelectric energy harvesting to supplement power needs.
