Titanium hydride nanoparticles and nanoinks for aerosol jet printed electronics

Abstract

Conductive inks commonly rely on oxidation-resistant metallic nanoparticles such as gold, silver, copper, and nickel. The criterion of air stability limits the scope of material properties attainable in printed electronic...

Aerosol‐Jet Printed Sensors for Environmental, Safety, and Health Monitoring: A Review

“…Despite their higher resistivity than silver‐ and copper‐based nanoparticle inks, advantages of corrosion resistance, biocompatibility, improved stability, and versatility can be potentially unlocked for their integration to numerous applications. [ 53 ] Carbon nanomaterials likewise remain a popular choice, as carbon inks, [ 54 ] graphene, [ 55 ] single‐walled carbon nanotubes (SWCNTs), [ 56 ] multiwalled carbon nanotubes (MWCNTs), [ 57 ] sorted semiconductive derivatives, [ 58 ] and metal composites [ 59 ] thereof. While carbon nanomaterials used alone perhaps cannot confer the same electrical performances as metallic‐based counterparts, they have several advantages when used in conjunction as conductive reinforcements and fillers due to their large surface area and superior mechanical properties; notwithstanding, silver–CNT composite inks have been demonstrated to have considerably lower resistivities than pristine silver inks by functioning as bridges across granular boundaries and defects in the printed lines.…”

3D printed electronics with nanomaterials

“…Among the non-contact printing technologies, two techniques gained a lot of interest: ink-jet printing 56,69,82,97,98 and Aerosol Jet Printing (AJP). 12,[99][100][101] The ink-jet technique can be additionally divided into Drop-On-Demand (DOD), continuous ink-jet printing and electrohydrodynamic jet printing, with the first being the most popular among the non-contact, maskless printing techniques. All these maskless techniques are often called digital printing, meaning they do not require additional mask fabrication, and the design can be directly printed on the Computer Numerically Controlled (CNC) setup.…”
