How it works?

1
A small portable laser scans the object and interacts with target molecules.
2
After the interaction, the reflected light carries the “fingerprints” of those target molecules back into sensor-on-chip and signal analysis is carried out, where molecular information is deciphered.
3
Sensing is performed in a fraction of a second, which means the sensor system-on-chip offers real-time measurements.

Methods of application

In-line

BROLIS sensor may be integrated directly into industrial interface either in-line providing the fluid/substance flow-through geometry or via bypass.This configuration has the following advantages:

  • Real-time composition monitoring
  • Absolute levels + trend
  • Direct feedback loop for process control
  • Process dynamics and log option
In vitro/off-line

For handheld, home use, portable off-line applications, where the sample is measured off-line. Be it a drop of blood, saliva or industrial process product/by product. A small portion of the sample is taken from the patient or industrial process, etc., and dispensed onto BROLIS sensor for spectroscopic measurement.

  • Ideal for portable applications
  • Quick measurement for composition
  • Lower cost
  • Simple use
In vivo

Non-invasive option for remote monitoring. Most challenging from technology point of view but most rewarding from user experience:

  • Real-time composition monitoring
  • Absolute levels + trend
  • No invasive procedure
  • Wearables, hearables, etc.

Technology highlights

BROLIS’ integrated sensor is based on swept-wavelength infrared laser absorption spectroscopy. Each molecule has a unique absorption spectrum due to its various rotational-vibrational movements. This unique absorption spectrum can be used as a fingerprint for species and concentration identification.

Brolis Sensor Technology owns unique GaSb/Si fully-integrated spectrometer-on-a-chip solution in the 1800 nm – 2400 nm spectral region for a wide variety of sensing applications. Our spectrometer on chip features all-in-house technology combination of:

 

  • Extremely broadband GaSb gain-chips grown by in-house MBE
  • Low noise, high yield uncooled GaSb photodetectors
  • Custom Si photonic integrated circuit technology
  • In-house GaSb/Si integration technology

To tackle the sensor problem, we created a technology that did not exist before. We build everything ourselves – from exotic GaSb (Gallium Antimonide) based material synthesis, to the world’s first ultra-widely swept hybrid GaSb-Si Photonics integrated laser.
The latter allowed us to create the world’s first laser-based sensors realized in a silicon photonics chip that is smaller than 5 sq. mm. All this know-how is proprietary to BROLIS and was developed purely in-house.
