1650nm SWIR SENSOR
ADR supply SWIR technologies (wavelengths range from 1,050-2,500 nm), gradually mature, and prices begin to reach feasible levels. A new applications, based on PPG technology adopt it. With improving algorithm, wearable devices are increasingly likely to feature PPG-based bio-sensing functions, which can measure not only heart rate and blood oxygen levels, but also other variables including body hydration as well as blood glucose, blood lipid, and blood alcohol levels in the

IR LED’s Improve Health and Environment Detection for Wearable devices. Via photoplethysmography (PPG), red light and infrared LED’s can receive date from the environment and measure biometric data including heart rate, blood oxygen, blood pressure and blood sugar level. Adopting the sensing components to wearable devices enables a wider range of applications. PPG is often obtained by using a pulse oximeter which illuminates the skin and measures changes in light absorption.
