LPWAN endpoints will need energy harvesting to achieve scale
summary
Claim: LPWAN deployments hit scale only if endpoints adopt energy harvesting. Cites 2 billion devices by 2025 and computes ~600 million batteries per year to replace with five‑year cells. Shows concrete examples: cattle tracker (750 µW average) costs ~$550 in battery replacements vs ~$50 with PV harvesting, Bluetooth beacon costs ~$250 vs ~$25. Uses PV, thermoelectric, vibration and RF harvesters plus PMICs with 94% conversion efficiency, 400 nA leakage and 3 µW–500 mW input range.
