New sensor chips: low-cost, smart and efficient

News - 19 November 2020 - Webredactie 3ME

A chip with a built-in sensor that is so sensitive that it registers a single coronavirus particle. At TU Delft, several researchers in various faculties, including Frans Widdershoven (EW), Peter Steeneken, professor Dynamics of Micro and Nanosystems and Murali Ghatkesar (PME/3mE) are working on this research.

Peter Steeneken: ‘We want to make the electrodes in such a way that they cause corona particles to attach themselves to them, so that we can count how many there are. Here too, CMOS technology is used. The smartness is already built in. We hope this will lead to a fast test. You could even incorporate them into face masks, so that you know whether you have Covid-19 or have been somewhere where it was in the air. The aim is to make such a test available for a couple of euros. We’re not there yet, though. The research is still at an early stage.
