Vorbeck Materials, based in Jessup, Md., manufactures and sells components that other businesses can use to produce wearable technology. Vorbeck specializes in graphene, a material that is one atom thick; the company produces graphene-based inserts that can monitor heart rate, temperature and other metrics. The company’s president, John Lettow '91, declined to share the names of Vorbeck’s business customers, but he said the company has been working with wearable technology for two to three years. “We’ve really been working to refine technology for true mass production in the apparel industry,” he said. Instead of a “T-shirt that can monitor all kinds of things but costs $300,” Vorbeck aims to help businesses reduce the price to, say, $30 or $40.
