GraphWear develops a non-invasive continuous glucose monitor (CGM) system consisting of a small wearable sensor made of graphene—a single-atom thin carbon sheet that can conduct electricity. The electrical field attracts molecules near the surface of the skin when activated, without breaking the skin. The sensor measures glucose molecules using nanotechnology and the readings are then sent via Bluetooth to the company’s mobile app. Users can track their glucose levels over time and receive real-time alerts at specified levels. The device comes in as a wristwatch attachment or an adhesive patch for the abdomen.
Funding and financials
In October 2021, the company raised USD 20.5 million in Series B funding led by Mayfield which was directed toward its pivotal clinical trials to determine how accurately the system can measure glucose levels. The company also planned to expand its product offering to cater to conditions such as heart disease or cancer detection and grow its employee base.
