Based on their combined expertise - Pi as a physicist and technologist with extensive electrical sensing knowledge and He as a former optoelectronics professor with experience in fibreoptics and on optical devices - the pair made two key discoveries that would later form the basis of their invention. First, that infrared light sensors - typically used by doctors for medical diagnoses - could be used to measure a finger pulse. Second, that a finger pressed against a sensor forces blood out of the capillaries. These findings led to the development of a new kind of optical sensor capable of capturing these changes, while simultaneously tracing a map of the user's fingerprint. The combination of these multiple technologies makes the world's first integrated Live Finger Detection (LFD) sensor developed by Pi and He almost impossible to deceive, setting a new benchmark for smartphone security.
Today, Pi is Chief Technology Officer at Goodix while He is R&D Director.
