Dynamical Biomarkers’ prototype, designed with the guidances of Harvard Medical School's Chung-Kang Peng, has a miniature EKG heart monitor, a small wireless blood pressure cuff, and a small thermometer to monitor key vital signs. An accompanying app takes users through a series of questionnaires on symptoms and other medical information, then guides them through using the devices. Tiny samples of blood can test for things like anemia and diabetes, and a miniature otoscope lets users take pictures of the inside of their ears—which are sent (via Amazon Cloud) to an algorithm that can detect infection. The technology is currently about 85 percent accurate when compared to standard physician diagnoses. A similar adapter takes a picture of moles and skin lesions to diagnose melanoma with 90 percent accuracy.
