生物可吸收电子（或瞬态电子）设备可以潜在地用于替代消费电子产品、植入式设备和数据安全中的持续制造设备，从而通过可控溶解减少电子废物和手术过程。印刷生物可吸收电子器件的最新发展导致了可用于制造互连、电路迹线和传感器的生物可吸收导电浆料或油墨，为生物可吸收电子器件制造中的主要互补金属氧化物半导体（CMOS）工艺提供了替代解决方案。然而，目前的生物可吸收糊剂和加工技术提供的电导率仍然远低于块状金属的电导率，需要进一步改进糊剂组成和工艺优化。本文旨在探讨生物可吸收图案的导电性测定中的几个影响因素，如糊剂组成和加工工艺。实验结果表明，按重量比为Zn：PVP：甘油：甲醇= 7：0.007：2：1的优化浆料组分可以产生适合于丝网印刷工艺的稳定的导电浆料。此外，通过结合热轧和光子烧结可以获得60，213.6S/m的高电导率。研究结果表明，采用丝网印刷、热轧和光子烧结等方法，通过优化浆料组成，可以实现大规模的瞬态电子器件，为进一步提高生物可吸收浆料或油墨的导电性，满足电子工业大规模生产和实际应用的需求提供了重要的实验依据和方法。
Bioresorbable electronics (or transient electronics) devices can be potentially used to replace build-to-last devices in consumer electronics, implantable devices, and data security, leading to reduced electronic waste and surgical processes through controllable dissolution. Recent development of printing bioresorbable electronics leads to bioresorbable conductive pastes or inks that can be used to make interconnects, circuit traces, and sensors, offering alternative solutions for the predominant complementary metal oxide semiconductor (CMOS) processes in fabrication of bioresorbable electronics. However, the conductivities offered by current bioresorbable pastes and processing techniques are still much lower than those of the bulk metals, demanding further improvement in both paste composition and process optimization. This paper aims at exploring several influential factors such as paste compositions and processing techniques in determining conductivities of bioresorbable patterns. Experimental results reveal that an optimized paste constituent with a ratio of Zn:PVP:glycerol:methanol = 7:0.007:2:1 by weight can generate stable conductive pastes suitable for a screen printing process. In addition, a high conductivity of 60,213.6 S/m can be obtained by combining hot rolling and photonic sintering. The results demonstrate that large-scale transient electronics can be obtained by combining screen printing, hot rolling and photonic sintering approaches with optimized paste compositions, offering important experimental proofs and approaches for further improving the conductivity of bioresorbable pastes or inks that can accommodate the demands for mass fabrication and practical use in electronic industry.
