IBM newly introduced "a first-of-a-kind 'fingernail sensor' prototype to help monitor human health" that takes the form of a small wearable.
While there are plenty of discreet wearable devices that are designed to detect vital signs, this prototype sets itself apart by continuously measuring the way a person's fingernail bends and moves, which indicates the strength of their grip. This project by IBM initially began to monitor people with Parkinson's disease. Some methods of measuring disease progression rely on skin-based sensors but these can cause complications like infections in elderly patients.
IBM's fingerprint sensor system works with AI to help clinicians to comfortably monitor individuals in their natural environments and potentially even spot some of the signs of a condition becoming better or worse. According to IBM, the team is working on making the lightweight, wireless and unobtrusive sensor even smaller.
