ISDI Case Study. Developing a NIR custom sensor for non-invasive glucose monitoring using Raman spectroscopy

ISDI were approached by RSP Systems to undertake a custom design for a near-infrared (NIR) sensor for their Touch Glucose Monitoring™ products.

This sensor, initially targeted for a small desktop system, will be used in a smartwatch-style device for non-invasive blood analysis based on Raman spectroscopy, eliminating the need to take frequent blood readings via finger-prick tests or patches.

For ISDI, this sensor design had several new features:

  • near-infrared sensitivity;

  • singleslope 16-bit ADCs;

  • an on-chip timing state machine;

  • micro-lenses;

  • direct connection to SoC (no FPGA).
