Printable Sensors research within the Sustainable Printable Electronics Research Group. Solution-processable semiconductors offer unique opportunities for the development of next-generation sensing technologies for applications including light, temperature and gas detection. Their compatibility with low-temperature, large-area manufacturing enables lightweight, flexible and cost-effective sensor platforms that can be integrated into a wide range of electronic systems.Our research explores the fundamental relationships between molecular design, thin-film processing and device physics to develop solution-processable semiconductors with tailored optoelectronic properties. By understanding how material chemistry and device architecture govern charge transport and photoresponse, we design high-performance sensors operating across the visible and near-infrared spectral regions, with a particular focus on organic phototransistors and multifunctional sensing platforms. This work aims to deliver highly sensitive, low-power devices while establishing the fundamental design principles that underpin the next generation of printable sensing technologies.
