Versatile carbon-loaded shellac ink for disposable printed electronics

Scientific Reports 2021 Volue 11, Article 23784

Emerging technologies such as smart packaging are shifting the requirements on electronic components, notably regarding service life, which counts in days instead of years. As a result, standard materials are often not adapted due to economic, environmental or manufacturing considerations. For instance, the use of metal conductive tracks in disposable electronics is a waste of valuable resources and their accumulation in landfills is an environmental concern. In this work, we report a conductive ink made of carbon particles dispersed in a solution of shellac. This natural and water-insoluble resin works as a binder, favourably replacing petroleum-derived polymers. The carbon particles…

Fully 3D Printed and Disposable Paper Supercapacitors

Advanced Materials 2021 Volume 33, Issue 26, Article 2101328

With the development of the internet-of-things for applications such as wearables and packaging, a new class of electronics is emerging, characterized by the sheer number of forecast units and their short service-life. Projected to reach 27 billion units in 2021, connected devices are generating an exponentially increasing amount of electronic waste (e-waste). Fueled by the growing e-waste problem, the field of sustainable electronics is attracting significant interest. Today, standard energy-storage technologies such as lithium-ion or alkaline batteries still power most of smart devices. While they provide good performance, the nonrenewable and toxic materials require dedicated collection and recycling processes. Moreover,…
