We developed a new optical sensor array and integrated light source (OSAILS) for oxygen detection. This stable, reproducible, and rapid sensor offers a low-voltage solution for various optical sensing applications.

Area of Science:

  • Optoelectronics
  • Chemical Sensing
  • Solid-State Devices

Background:

  • Optical sensor arrays are crucial for various detection applications.
  • Existing technologies may face limitations in stability, response time, or power consumption.

Purpose of the Study:

  • To introduce a novel, solid-state, integrated optical array sensor platform.
  • To demonstrate the utility of this platform for quenchometric O2 detection.

Main Methods:

  • Development of a solid-state optical sensor array integrated with a light source (OSAILS).
  • Testing of the OSAILS platform for oxygen detection using quenchometric principles.

Main Results:

  • The OSAILS operates at low voltages (3-5 V dc).
