Finnish innovation shrinks lab-grade imaging to fingertip size for everyday use

A startup from Aalto University has turned complex laboratory imaging into a tiny, affordable sensor – opening the door to new uses in health monitoring and food quality control.

Agate Sensors is commercializing a breakthrough that brings the power of hyperspectral imaging from the laboratory to entirely new markets – in an unprecedented size and price range.

Traditionally, hyperspectral cameras rely on large optical and mechanical components to scatter and filter light. Their size ranges from that of a toaster to that of a suitcase, with prices starting at 50,000 euros.

Agate Sensors’ version fits on your fingertip and is designed to be affordable enough that it could one day be included in every mobile phone.

“In the future, you’ll be able to use your phone to check the ripeness of an avocado or the freshness of fish at the grocery store,” Mikael Westerlund, the company’s chief business officer, explains. “A remote doctor could use data from a smartwatch to monitor your stress levels, blood pressure or iron deficiency. Top athletes could track their lactate levels, and forest owners could monitor the condition of their trees using drones.”

The project reflects Finland’s strength in deep-tech innovation, where university research is sparking globally relevant startups.
