In this work, we present a do-it-yourself (DIY) approach for the environmental-friendly
fabrication of printed electronic devices and sensors. 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.
