Proteus Digital Health was a company that focused on developing digital medicine products designed to integrate medicine with ingestible sensors. These products aimed to help patients, healthcare providers, and health systems achieve better health outcomes. The cornerstone technology of Proteus was its ingestible sensor, which could be embedded in medications to track if and when patients took their prescribed medications. This data could then be integrated into a digital app to help manage and improve treatment outcomes. Although Proteus Digital Health had made significant advances in digital health innovation, please note that the company filed for bankruptcy in 2020 and was subsequently acquired by Otsuka Pharmaceutical.
