A Biodegradable and Conductive Ink as the Basis for Transient Electronics

Year: 2023

Presenter Name: Sammi Yu

The risk of infection from implants is compounded in cases with permanent implants because a second removal surgery is required. With second surgery, unwanted risks and infections are introduced which can then lengthen the hospital stay, increase healthcare costs, and endanger patients' lives. To address this risk of second surgery infections, transient electronics are a potential solution by mitigating retrieval surgery completely. Transient electronics are defined by the ability to break down into non-toxic elements and dissolve, resorb, or physically disappear in physiological environments in a controlled manner. Many materials have these properties of biodegradability and non-toxicity however, they have not been discovered or synthesized before. Here we show the combination of a polymer called PBTPA and molybdenum (Mo) to create a biodegradable and conductive ink. We determined a synthesis process to mix specific ratios of Mo to PBTPA to optimize the ratio for conductivity and printability. By printing the ink using additive manufacturing, it allows us to create personalized electronics. Future applications of this ink may be used to print sensors that monitor the healing process of joints after surgery.
