High-speed PIN photodiode delivers enhanced sensitivity for visible light

Health and fitness trackers remain popular and nobody likes getting punctured, twin incentives to continuously increase the accuracy of noninvasive medical and health monitoring technology. Some of these devices rely on clever optical techniques to make their measurements. For these applications, Vishay Intertechnology Inc. has introduced a high-speed silicon PIN photodiode with enhanced sensitivity for visible light.

The ability to monitor heart rates is migrating from single-purpose devices made by companies like Fitbit and Xiaomi to general-purpose smartwatches (e.g., the Garmin Vivoactive 3). Smartwatch sales are expected to grow vigorously over the next few years, according to Gartner  Read more...
