Ultra high performance in life sensing

Senbiosys is a spinoff of the Swiss Federal Institute of Technology (EPFL). Born in IMT, an institute famous for micro and nano engineering, next to the CSEM, we’ve quickly developed a strong expertise embedded into a startup excelling in ultra-high performance light sensing and ultra-low noise. We have already beaten several world records.

Our vision is to design the next generation of sensors with the highest efficiency and the lowest power consumption.

Higher performance in sensors reliability, accuracy and efficiency is needed to accelerate the growth of IoT for the health market. We’ve developed the next generation of PPG sensors to address these challenges and enable the continuous tracking of key vitals.”

Senbiosys has developed SB200, a new ultra high performance chip that measures efficiently the Photoplethysmography (PPG) signal.

SB200 brings the following unique characteristics to the market:

Precise and reliable PPG signal

A precise and reliable PPG signal, restored with an extremely low noise and a high quantum efficiency

Reduced power consumption

A significantly reduced power consumption, at a level never reached before

High miniaturization

A high miniaturization through more integration
We have an evaluation kit that allows testing the SB200 PPG sensor under various conditions with a simple user interface


  • 5.9 x 6.9 mm² PPG module, with
    • 1x SB200 PPG sensor (2,4 x 2,4 mm²)
    • 1x red + green LEDs
  • SPI-USB interface adaptor with 2 LDOs for 1.8V supply and 2.4V ADC reference.
  • SPI-USB cable (FTDI), with
    • 4 wires SPI
    • FIFO-full signal handling
    • Reset control
    • 3,3V-GND
  • Software for the module settings, data acquisition and processing
