Dutch startup launches biomedical ‘lab on a chip’
The sensor, which Onera calls a Biomedical-Lab-on-Chip, was launched at CES 2022 this week and acquires and processes multiple biosignals in a wide range of wearable health applications and devices.
The chip provides ten readouts for ExG, covering EEG, ECG, EMG, and EOG, two bioimpedance readouts, and two readouts for photoplethysmography (PPG), the optical technique used for SPO2 sensors to measure blood oxygen through the skin.
The data is processed by on-chip digital filters and accelerators, supported by an ARM Cortex M4 floating point core. The chip features several standard wired interfaces such as UART, SPI, I2C, and I2S and operates from a single power source which can be anything between 0.8V and 3.6V as the power management is also integrated on-chip. Additional SRAM and embedded flash supports the large number of data streams with accurate data-synchronization as an essential feature.

“We are thrilled to introduce Onera Biomedical-Lab-on-Chip at CES 2022 in Las Vegas this week. It’s the perfect opportunity to showcase our chip to the wearables ecosystem,” said Ruben de Francisco, Founder and CEO of Onera, which has a focus on sleep analysis systems. “Our highly integrated and comprehensive biosignal sensor hub is a unique solution that promises to revolutionize this competitive field. It combines clinical-grade physiological measurements and analysis with ultra-low-power consumption, enabling the development of miniaturized and high-quality wearable devices. Launching this powerful chip as a stand-alone product within our portfolio, not just as part of our innovative Onera diagnostic and monitoring solutions, is yet another exciting step for our company.
The Dutch company used its deep tech roots and close partnership with Belgian lab imec to develop the ultra-low-power biosignal chip.
