Abstract

Bioresorbable electronics technology can potentially lead torevolutionary applications in healthcare, consumer electronics, and datasecurity. This technology has been demonstrated by various functionaldevices. However, majority of these devices are realized by CMOS fabricationapproaches involving complex and time-consuming processes that are high incost and low in yield. Printing electronics technology represents a seriesof printing and post processing techniques that hold promise to make highperformance bioresorbable electronics devices. But investigation of printingapproaches for bioresorbable electronics is very limited. Here wedemonstrate fabrication of conductive bioresorbable patterns using aerosolprinting and photonic sintering approaches. Experimental results andsimulation reveals that ink compositions, photonic energy, film thickness,and ventilation conditions may influence the effect of photonic sintering. Amaximum conductivity of 22321.3 S/m can be achieved using 1 flash withenergy of 25.88 J/cm$^{2}$ with duration of 2 ms. By combining two cascadedsintering procedures using flash light and laser further improve theconductivity to 34722.2 S/m. The results indicate that aerosol printing andphotonic sintering can potentially yield mass fabrication of bioresorbableelectronics, leading to prevalence of printable bioresorbable technology inconsumer electronics and biomedical devices.
