This data set contains the data collected during the FNS project Green Piezo (Grant no. 179064) in association with the recent publication entitled “3D printing of customizable transient bioelectronics and sensors”. This work aims to study and demonstrate the fabrication by 3D printing of devices made of transient materials, i.e. materials that can break down and degrade in an environment of choice. Biodegradable electronic devices have potential in tackling the issue of electronic waste and present an opportunity for new types of implantable and/or wearable devices that can resorb after their lifecycle is completed. A bioresorbable elastomer and a conductive carbon-based ink are printed by direct-ink writing, thanks to an in depth study of their dispense behavior. Several sensors are shown as demonstrators (strain, pressure, electrodes). The data that was collected in the frame of this work is present in this repository. More information about the contents of the dataset is present in the included README file.
