Swiss startup claims low power PPG plus ToF sensor

Swiss startup claims low power PPG plus ToF sensor

Technology News |
Senbiosys SA, a 2017 spin-off from Ecole Polytechnique Fédérale de Lausanne (EPFL), has developed a chip that can measure both heart rate, and oxygen level using both the photoplethysmography (PPG) and time-of-flight (ToF) signals.

The chip, Senbio1, also measures ambient light. Innovations in the Senbio1 chip are the subject of a paper due to be presented at ISSCC 2019 under the title “A 2.6 microwatt monolithic CMOS photoplethysmographic sensor operating with 2 microwatt LED power.”

The company claims to have developed the most comprehensive set of functions in a light sensor that is the most compact and most energy efficient.

The company was co-founded by Assim Boukhayma, Antonino Caizzone and Professor Christian Enz. The company is led by Montassar BenMrad who serves as CEO. Professor Enz is the director of the Institute of Microengineering (IMT) at EPFL and the head of the Integrated Circuits Laboratory (ICLAB) and serves Senbiosys as scientific advisor.
