PiezoSkin team has developed a consolidated fabrication protocol of flexible piezoelectric nanogenerators and sensors. The devices are based on a polymeric substrate and a highly flexible thin films structure (thanks to an optimized reactive sputtering deposition), composed of Aluminum Nitride, as piezoelectric layer, and Molybdenum as electrode. The extremely low thickness of the whole structure (below 30 µm) makes the product the thinnest piezoelectric transducer in the market.
PiezoSkin is a startup based in Lecce and established as a spin-off from the Center of Biomolecular Nanotechnologies (CBN) of the Istituto Italiano di Tecnologia (IIT). The CBN has developed over the last 5 years technologies for harvesting energy and sensing from mechanical sources (such as vibrations and fluid flows) and by human body movements. To this aim, Piezoskin has developed the whole fabrication protocol for soft piezoelectric transducers, from a customizable design to device production, characterization and test.
