Technology Features & Specifications
This spectrum sensor does not use an optical grating that is used in conventional spectrometers for spectral analysis. Instead, it has a bespoke filter array based on an innovative plasmonic filter.
Developed using digital nano fusion technology, this miniaturised low cost spectrometer measures individual light wavelengths that selectively pass through nanostructures to determine its makeup. It is accurate to 1 nm with 10nm resolution.
The spectrometer has a built-in advanced spectral signal processing and standard SPI or UART interface, and is individually calibrated nano-accurately and provides device-to-device repeatability. The spectral databases for applications are portable and reusable, as the data measured by this spectrometer is compatible with the spectrum data measured by conventional optical spectrum analysers.
This spectrometer technology is versatile and offers the potential to provide spectral measurement and analysis in the following target markets:
- Health: Simultaneous measurement of heart rate, heart rate variability (HRV), oxygen saturation (SpO2), blood pressure and glucose (ready soon)
- Plant and food: Plant and crop health, measure ripeness and suitability for harvest, food safety and quality
- Environment: Water and air quality, solar energy, crop health
- Personalised beauty: Skintone and skin spectra, to enable the purchase of the suitable skincare or accurate shade of colour for cosmetic products
Market Trends and Opportunities
The spectral sensor market is anticipated to be around $4~8 billion in 2026, as a key enabling sensing element of wearable health monitoring market($140B), Agri-Food quality and safety sensing market($16B), environment monitoring market($12B), and more.
This ultra-compact and low-cost spectrometer technology offers advantages over discrete optical sensing with its broadband snapshot with accurate, multi-function noise-robust information. In terms of measurement, it offers the following benefits:
