“Battery‑free” doesn’t mean “no energy.” It means sensors harvest energy on demand (often from sub‑1 GHz RF) and buffer it (e.g., in capacitors/supercapacitors) to take a measurement and backscatter the data. That subtle difference is what makes deployments practical, compliant, and maintenance‑free.

Battery free wireless relay

From Sensing to Acting At Kliskatek, we’ve spent years developing batteryless wireless sensors that bring visibility to the physical world. But sensing is only half the story. The next frontier is actuation—using harvested energy not just to observe, but to interact with the environment. Imagine switching a circuit on or off—without wires, without batteries, and using only the energy … Read more
