Our core technology

Active Thermal®

A patented sensing technology utilising heat. Potential for many different applications where smart heat sensing is important — security applications, AI applications and more. Backed by 25+ years of R&D and a current portfolio of 14 patent families, with 38 granted patents and the Active Thermal® trademark.

How it works

Heat, measured — not light, not charge.

Heat, measured at every pixel: a thin heater sits behind the surface. Where a fingerprint ridge touches, heat leaves the sensor; where a valley floats in the air gap, it stays. Each pixel reads that difference and the pattern of ridges and valleys emerges as an image. Because it is heat — not light or sound — it is unaffected by dirt, water, oil, bright sunlight or finger age, and the same process builds sensors on rigid and flexible substrates alike.

Cross-section of a fingerprint resting on an Active Thermal sensor: four pixels, each with a micro heater and a temperature sensor, under the ridges and valleys of a finger. Below, photographs of rigid and flexible fingerprint sensors.
01

Emit

Each pixel in the thin-film array releases a tiny, controlled pulse of heat.

02

Measure

Ridges touching the sensor draw heat away faster than the air gaps of valleys.

03

Image

The heat-transfer map becomes a high-quality fingerprint image, up to 500 ppi.

04

Verify liveness

Human skin reacts to heat differently from silicone, gelatine or prints — spoofs are rejected in hardware.

Why Active Thermal

Secure & future-proof

In-built hardware anti-spoofing and leading liveness detection, proven in national ID, banking and government programs.

Cost-effective to integrate

Thin, energy-efficient sensors on LTPS thin-film-transistor glass fit standard display manufacturing lines and lower total solution cost.

Built for harsh conditions

Immune to direct sunlight, works indoors and outdoors, in humidity and with sweaty fingers, with low sensitivity to electrical noise.

Why it stands apart

In the example under you can see the differences between the three different sensor types: Optical, Capacitive, and Active Thermal.

Comparison of Active thermal, Capacitive and Optical fingerprint sensing: each column shows a cross-section of a finger on the sensor — heat sensors, capacitors, or a prism, lens and CMOS chip — with notes on cost, form factor, sunlight, moisture and noise. Along the right, eight advantages: large sensing area and ultra-slim form factor, cost effective, certified by FBI (PIV) and STQC L1, MOSIP and NIBSS Nigeria, immune from sunlight interference, works well with moisture and sweaty fingers, low sensitivity to electrical and environmental noise, high resolution imaging with low power consumption, and support for both rigid and flexible formats.
