Casimir develops micro‑scale energy‑harvesting chips that draw power from quantum fields using proprietary Casimir cavities, eliminating the need for batteries, cords, or charging. The 5 mm × 5 mm “microsparc” chip delivers a continuous 1.5 V output at 25 µA, enabling devices to operate indefinitely in any lighting condition. The company is currently prototyping the technology with university partners and plans to launch the first commercial version in 2026.

Problem
Many low‑power electronic devices, especially in IoT and wearable markets, rely on batteries or external power sources that require periodic replacement, charging, or exposure to light, limiting device lifespan and deployment flexibility.
Solution
Casimir creates micro‑scale energy‑harvesting chips that convert energy from quantum Casimir fields into continuous electrical power. Their 5 mm × 5 mm “Microsparc” chip delivers a steady 1.5 V at 25 µA without the need for batteries, cords, or sunlight, enabling devices to operate indefinitely in any lighting condition. The chips are fabricated using proprietary cavity designs and university‑partner clean‑room processes, ensuring reliable performance at a compact footprint. Future chip assemblies will stack multiple layers and dice to increase output by up to 100× while maintaining the same footprint, providing scalable power for a range of applications. By offering a self‑sustaining power source, Casimir aims to replace traditional storage and charging solutions across consumer electronics and IoT devices.
Target Audience
Primary customers are manufacturers of low‑power IoT sensors, wearables, and other embedded electronics that require long‑term, maintenance‑free power.
