Patterned Coatings Based On 2D Materials Benzoxazine Resin Hybrids For Broad Range Pressure Detection
Summary of the project
The development of pressure sensors and, in particular, of electronic skin, is fundamental to the interfacing between human bodies and the outside world, namely in prosthetics and biomedical applications.
To mimic the tactile sensing properties of natural skin, one should develop large arrays of pixels, each one acting as an independent pressure detector supported on a flexible and stretchable substrate.
PROSPECT targets an innovative generation of patterned coatings based on benzoxazine thermo- and photo-resist matrices incorporating electrically conductive 2D layers for wide-range pressure sensing applications.
Guided by theoretical modelling, we will design and synthesize novel benzoxazine monomers equipped with functional groups that will both serve as reticulation nodes and as centres for the (non-)covalent anchoring of electrically active (Reduced) Graphene Oxide, (R)GO, flakes.
PROSPECT aims at fabricating sensors that can accurately measure pressures both in the medium-pressure regime (10–100 kPa) suitable for object manipulation and in the low-pressure regimes (<10 kPa) typical of gentle touch.
The targeted devices, which will operate at low voltage for low-power consumption and will be amenable to large‐scale fabrication process, provide an appealing solution for technological applications in wearable health‐monitoring as Point-of-Care, multimotion detection robotics, and the Internet of (Every)Things.
