Description of the activity
Nowadays optoelectronic systems used in several sensing application demand high integrability with flexible substrates for application in biomedical sensors, artificial skins, smart patch etc. This approach allows fabrication of systems that can bend, flex, and twist without any performance alteration.
The research activity aims to integrate light-emitting devices, optical elements, and photoelectric devices on plastic materials such as PDMS and PMMA. In particular, a holographic approach is used to realize flat, light and highly efficient diffractive optical components (lens, beam splitter, etc).
The systems allow the propagation of light through a transparent substrate, the interaction of light with optical components for its manipulation, the interaction of light with sensors and the optical reading of the sensor response.
