PIEZOSKIN-CUSTOMIZED 3D-PRINTED MEMS PACKAGE WITH ELECTRIC PADS
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). Over the last five years, the CBN has developed technologies for harvesting energy and sensing from mechanical sources (such as vibrations and fluid flows) and human body movements. To this aim, Piezoskin has developed a consolidated fabrication protocol for soft piezoelectric transducers, from a customizable design to device production, characterization, and testing..
The devices created by Piezoskin are based on a polymeric substrate and a highly flexible thin-film structure, comprised of Aluminum Nitride as a piezoelectric layer and Molybdenum as an electrode. The extremely low thickness of the whole structure makes the product the thinnest piezoelectric transducer on the market today, ideal for the wearable transducers and next-generation micro-electro-mechanical systems (MEMS) used in multiple applications — especially biomedical.
In manufacturing ohmic-contact MEMS, the metal contact is one of the most crucial parts, as it determines the device’s performance and reliability. This issue is especially important in the manufacture of devices that are soft and flexible, as producing electrical connections becomes difficult due to the technical constraints involved. Piezoskin therefore turned to Nano Dimension, requesting a solution that would optimize the process.
