Casimir is commercializing the MicroSparc chip, which the company says harvests energy directly from quantum vacuum fields to provide continuous power without batteries or charging cycles. The technology and fabrication work referenced DARPA-supported nanofabrication and was recently described in a peer-reviewed paper in Physical Review Research. The project is led by Harold “Sonny” White, a physicist formerly with NASA. Casimir announced an oversubscribed $12 million seed round to fund efforts to bring the chip to market. The company has positioned this financing as seed equity and disclosed a wide group of participating investors but did not report revenue, users, or a prior valuation in the article.
