- Energy Harvesting and
- Similarity: Both involve efficiently using unstable energy.
- Difference: Energy Harvesting requires a stable power source.
- Three types:
- Electromagnetic Induction (high power, short distance)
- Examples include Qi.
- Power is transmitted and received by connecting coils.
- There is also an improved version called Resonant method.
- Microwave (low power, long distance)
- Similar technology used in Energy Harvesting to convert radio waves into electricity.
- RFID also uses this technology to receive and convert microwave energy.
