The setup consists only of an automated handwriting robot and pens filled with silver conductive inks. Here, we thoroughly studied the fabrication technique and different optimized parameters. The best-achieved results were 300 mΩ/sq as sheet resistance with a printing resolution of 200 µm. The optimized parameters were used to manufacture fully functional electronics devices: a capacitive sensor and a RFID tag, essential for the remote reading of the measurements. This technique for printed electronics represents an alternative for fast-prototyping and ultra-low-cost fabrication because of both the cheap equipment required and the minimal waste of materials, which is especially interesting for the development of cost-effective sensors.}, organization = {TUM Graduate School and by the European Commission through the fellowship H2020-MSCA-IF-2017-794885-SELFSENS}, publisher = {MDPI}, keywords = {Additive manufacturing}, keywords = {Ball pen}, keywords = {Flexible substrate}, keywords = {Printed electronics}, keywords = {Silver nanoparticles}, title = {Optimization of a Handwriting Method by an Automated Ink Pen for Cost-Effective and Sustainable Sensors}, doi = {10.3390/chemosensors9090264}, author = {Loghin, Florin and Fernández Salmerón, José and Lugli, Paolo and Becherer, Markus and Falco, Aniello and Rivadeneyra Torres, Almudena}, }
