Emerging Tech The Biggest Lie About Battery‑free Wearables?
Battery-free wearables are not truly charger-less; 2024 IDC data shows that 18% of component cost is added by required capacitors, and real-world energy harvesters only offset a fraction of the load. The claim of unlimited runtime ignores the engineering trade-offs that still demand power storage and regulatory approvals. Battery-Free Wearable
