|Infineon and GoerTek optical sensor solutions deliver precise, ultra-low power heart rate monitoring for smart devices|
|Munich, Germany – February 19, 2016 – Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) and GoerTek Inc. (SHE: 002241) today launched two high-resolution, highly integrated optical sensors. The optical chips deliver the precise measurement, small size and ultra-low power consumption demanded by ambient light sensing, proximity detection, heart rate and pulse oximetry monitoring applications in smart devices. The sensor solutions offer best-in-class performance for headphones, fitness bands, smart watches and phones. They are integrating three LED outputs, a photodetector, a low-noise analog front-end, a digital interface and a state machine into a single die. For best application results the bare die is either packaged with an infrared or a green LED or can drive up to three external LEDs.
The sensors offer a fully integrated solution for optical heart rate measurement featuring an I²C interface for a programmable sample rate of up to 256 per second. This allows a significantly better signal-to-noise ratio (SNR) than discrete alternatives. Additionally, monitoring algorithms can filter out motion artifacts and deliver precise heart rate and pulse oximetry measurements during exercise. High optical sensor resolution enables accurate measurement across the widest possible variety of skin types, while high optical sensitivity reduces photo diode area and drives down LED power consumption with a typical 300 µA LED current on fair skin. A standby current of just 0.3 µA further reduces power consumption.
Infineon and GoerTek sensor solutions are available either as bare die or as packaged products with application algorithm from Infineon’s long-term partner GoerTek. Packages measure just 3.94 mm x 2.36 mm x 1.35 mm. Packaged samples are available now, with volume production targeted in August 2016. In addition to the bare die chips from Infineon, GoerTek is offering starter kits and demonstration boards for designers looking to rapidly evaluate and test the technology for use in their smart applications.
Infineon Technologies AG is a world leader in semiconductor solutions that make life easier, safer and greener. Microelectronics from Infineon is the key to a better future. In the 2015 fiscal year (ending September 30), the company reported sales of about Euro 5.8 billion with some 35,400 employees worldwide. Infineon is listed on the Frankfurt Stock Exchange (ticker symbol: IFX) and in the USA on the over-the-counter market OTCQX International Premier (ticker symbol: IFNNY).
