Imperceptible and Disposable Humidity and Temperature Sensors with Low Environmental Footprint Enabled by Aerosol Jet Printing and Cellulose-Based Substrates.

ABSTRACT: The continuous growth of the electronics industry requires a reevaluation of traditional materials and manufacturing techniques to address the rising issue of electronic waste (e-waste). Environmental monitoring devices, which provide valuable insights into factors such as humidity and temperature, currently rely on non-degradable substrates and toxic metals, significantly contributing to plastic and electronic waste. Furthermore, conventional manufacturing techniques like screen printing, while effective, are limited in their ability to produce miniaturized, high-resolution features. Here, aerosol jet printing is used to fabricate devices for humidity and temperature monitoring, enabling minimal footprint (99.75% material reduction vs other printing methods), and precise patterning of fea
