February 23, 2016 Munich, Germany, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) and GoerTek Co. (SHE: 002241) today jointly launched two high-resolution, highly integrated optical sensor. The optical chip can meet the wearable device in heart rate and pulse oximetry monitoring applications for precision measurement, compact shape and ultra-low power requirements. The sensor solution allows headset, wrist strap and a fitness smartwatch has first-class performance. They are three LED output, a photodetector, a low-noise analog front end, a digital interface and a state machine integrated in a dice. For best application results, the die can be used with infrared or green LED integrated package can also be individually packaged to drive up to three external LED.
The sensor is a fully integrated optical heart rate measurement solutions, with up to 256 times / second programmable sampling rate, and standard I2C digital interface. This makes it significantly better than having a separate sensor signal to noise ratio (SNR). In addition, monitoring algorithm filters out motion artifacts, such that during exercise can also be accurate heart rate and pulse oximetry. High resolution optical sensor can be carried out on various types of skin accurately measured, and the high sensitivity of the optical area of the photodiode can be reduced, reducing power consumption LED - applied to the skin of the white LED current is typically 300μA. Only 0.3μA standby current can be further power savings.
Availability
Infineon and GoerTek's sensor solutions may die, it can be packaged products and applications algorithm provided by Infineon long-term partner Goertek company. Package size of only 3.94mmx2.36mmx1.35mm. Currently available packaging samples, it plans to mass production in August 2016. In addition to die Infineon, the company also offers Goertek Starter Kits and Demo Boards wishing to quickly evaluate and test designers can use in wearable device technology.
