Application of flexible flat panel display technology to wearable biomedical devices

How the application of commercial (thin film) flat panel display technology, used in the production of flexible displays and flexible digital X-ray detectors, can also be applied to reduce the manufacturing cost of wearable biomedical devices, as well as potentially improve their diagnostic functionality, is explored. As a technology platform to evaluate the presented new concept, a prototype photoplethysmograph biosensor using a flexible organic light-emitting diode display and pin photodiode (thin film) sensor technology for optical heart rate monitoring is developed.
