The development of widely available and inexpensive physical and chemical transducers is of great importance for future devices that assist us in the field of medicine, agriculture, security, as well as environmental monitoring and protection.
Hybrid organic/inorganic nanoparticle composites own unique and tunable electronic, mechanical, optical and sorption properties, making them promising candidates for the development of high-performance sensors. In this presentation I discuss recent investigations on the strain-sensitive charge transport in cross-linked gold nanoparticle networks and present their integration into wearable transducers for the detection of physiological signals. These encompass the faint strain occurring at the skin surface above blood vessels through which a pulse wave passes, or strains in gesture sensing.[1] Further, the use of freestanding nanocomposites for micro- and nanoelectromechanical systems (MEMS/NEMS), such as pressure sensors with record sensitivities[2] and electromechanical transducers for VOC detection,[3] will be discussed.
Eventually, I will present recent works on nanocomposite-based chemiresistive sensors for VOCs. Here, our research focuses on the exploration of dynamic processes occurring upon sensor exposure to analytes, their monitoring and utilization for analyte recognition using machine learning.[4] Also current developments of plasmonically photoactivated gas sensors are discussed.[5]

Hendrik Schlicke is a research group leader at Leibniz IPF Dresden since 2023. Following a research stay at the UC Berkeley he received his M.Sc. from the University of Hamburg in 2013. Afterwards he completed his PhD (2017) at the University of Hamburg working on freestanding gold nanoparticle composites and their application in nano- and microelectromechanical systems. Moving to the Fraunhofer Center for Applied Nanotechnology (CAN) as project leader in 2018, his work focused on nanoparticle-based optoelectronic components, such as polarized-light emitting quantum- rod LEDs and near-infrared quantum dot emitters for miniaturized spectrometry.
At Leibniz IPF his research group focuses on the integration of nanomaterials into novel device types for exploration and application of new transduction schemes in chemical, mechanical and optoelectronic sensing.
