Aerosol Printing and Photonic Sintering of Bioresorbable Zinc Nanoparticle Ink for Transient Electronics Manufacturing
Bioresorbable electronics technology can potentially lead to revolutionary applications in healthcare, consumer electronics, and data security. This technology has been demonstrated by various functional devices. However, majority of these devices are realized by CMOS fabrication approaches involving complex and time-consuming processes that are high in cost and low in yield. Printing electronics technology represents a series of printing and post processing techniques that hold promise to make high performance bioresorbable electronics devices. But investigation of printing approaches for bioresorbable electronics is very limited. Here we demonstrate fabrication of conductive bioresorbable patterns using aerosol printing and photonic sintering approaches. Experimental results and simulation reveals that ink compositions, photonic energy, film thickness, and ventilation conditions may influence the effect of photonic sintering. A maximum conductivity of 22321.3 S/m can be achieved using 1 flash with energy of 25.88 J/cm2 with duration of 2 ms. By combining two cascaded sintering procedures using flash light and laser further improve the conductivity to 34722.2 S/m. The results indicate that aerosol printing and photonic sintering can potentially yield mass fabrication of bioresorbable electronics, leading to prevalence of printable bioresorbable technology in consumer electronics and biomedical devices.
