CASIMIR

What CASIMIR does

Casimir, Inc. is a Houston, Texas-based deep-technology company developing the MicroSparc chip, described as the world's first quantum vacuum energy harvester. The chip exploits the Casimir effect through engineered Casimir cavity nanostructures — metal plates fixed to a silicon substrate with isolated nano-pillars in the center gap, creating an energy differential that allows continuous electron flow. The first-generation device measures 5mm x 5mm and produces 1.5 volts at 25 microamps without batteries, cords, or external charging, with the company targeting multi-layer architecture and die-stacking to scale output by up to 100x in the same footprint.

The technology was incubated at the Limitless Space Institute (LSI), a nonprofit founded by Dr. Kam Ghaffarian, and underpinning nanofabrication work was funded by DARPA's Defense Sciences Office. Founder and CEO Dr. Harold "Sonny" White, a former NASA advanced propulsion researcher, published a peer-reviewed theoretical framework for the approach in Physical Review Research in March 2026. Core intellectual property rests on proprietary Casimir cavity designs manufactured and tested iteratively at university clean rooms.

Casimir is pre-revenue and pre-commercial. Its stated business model is dual-track: near-term hardware sales of MicroSparc chips and hybrid power systems into ultra-low-power applications (IoT sensors, wearables, tire pressure monitoring systems — a ~$10B initial market), with a longer-term shift toward licensing royalties as the technology scales into consumer electronics, EVs, residential/commercial energy systems, and data centers (a combined $67B+ TAM). Commercial launch is targeted for 2028, supported by a $12M oversubscribed seed round led by Scout Ventures in May 2026.

Core offering

Casimir develops and manufactures the MicroSparc quantum vacuum energy chip, a 5mm x 5mm semiconductor device that harvests continuous electrical power from quantum vacuum fields using proprietary engineered Casimir cavity nanostructures. The chip produces 1.5 volts at 25 microamps without batteries, cords, or charging and is targeted at ultra-low-power electronics including IoT sensors, wearables, and tire pressure monitoring systems, with a roadmap to scale across consumer electronics, electric vehicles, and large-scale energy systems.

Product overview

CASIMIR offers a single unified product: the MicroSparc quantum vacuum energy chip. This semiconductor chip harvests energy from quantum vacuum fields using proprietary Casimir cavity nanotechnology to produce continuous electrical power without batteries, cords, or charging. The technology is engineered to scale across power levels — from microwatts/milliwatts for small devices (IoT sensors, wearables, tire pressure monitors), to watts for consumer electronics and electric vehicles, to kilowatts/megawatts for homes, data centers, and commercial aircraft. The company’s multi-layer Casimir chip architecture and advanced die-stacking techniques enable 100x power density scaling in the same footprint. The first-generation MicroSparc targets commercial availability by 2028, with initial hybrid power systems designed to work alongside existing batteries.

Products and services

• MicroSparc quantum vacuum energy chip The MicroSparc is the world's first quantum vacuum energy chip that harvests continuous electrical power from quantum vacuum fields using the Casimir effect. It measures 5mm x 5mm, weighs 1.44 ounces, and produces 1.5 volts at 25 microamps without batteries, cords, or charging. It is designed for ultra-low-power applications including IoT sensors, wearables, tire pressure monitoring systems, smoke detectors, hearing aids, and other devices where battery replacement is costly or impractical. The technology scales from microwatts/milliwatts (first generation) to watts (consumer electronics and EVs) and ultimately kilowatts/megawatts (homes, data centers, commercial aircraft) through multi-layer Casimir chip architecture and advanced die-stacking. Initial products are hybrid power systems designed to work alongside existing batteries.
