Thin-film transistors

Next-level TFT applications
for healthcare, security and energy

As a forerunner in oxide thin-film transistors (TFTs) for displays and imagers, Holst Centre is now pushing this proven technology into new promising territories, for example to create next generation optical sensors and ultrasound transducers.

Holst Centre has long set the pace in the development of oxide and organic thin-film transistors (TFTs) for displays, imagers and many other applications. We continue to push TFT performance forward, for example by using sALD for semiconductor and dielectric layers. This allows high-mobility semiconductors to be created at process temperatures below 200°C – ideal for applications on low-cost polymer foils. We are also pioneering new materials such as p-type oxide semiconductors, which could pave the way towards CMOS-style TFT applications

Security solutions

To address the need for heightened security, we have developed expertise in large-area, high-resolution optical and capacitive sensors. These are ideal for under-display fingerprint and biometric detectors that protect against spoofing and security breaches. They deliver high resolution in sizes large enough for palm and four-finger scans and yet are thin, lightweight and (semi-)transparent, so can be integrated into various electronics and intelligent surfaces.

Next-gen ultrasound

With our unique thin-film electronics, Holst Centre makes it possible to create large-area, flexible transducer arrays that will allow hands-free ultrasound systems that do not require a skilled operator. The ultrasound-on-foil technology allows thousands of individual transducers to be integrated into an adhesive patch. Such patches can be used, for example, for at-home monitoring of high-risk pregnancies.

New ventures

At Holst Centre we want to continue to advance technology in healthcare. The same technology used to create foldable displays and semi-transparent imagers will be applied to innovative microfluidics, bioelectronics and potentially even brain/computer interfaces.
