Wood-n’t you imagine it: cellulose-based 3D printed electronics produced at SFU


Right after looking at the smart wooden at CES 2019 we realized it would only be a issue of time right before a 3D printed wise wood came alongside.

For some time it seems, teams at Simon Fraser University (SFU), British Columbia, and the Used Wooden Resources Laboratory at the Swiss Federal Laboratories for Resources Science and Know-how (EMPA) have been operating on their individual wooden-derived electronics.

Employing 3D printing certification, the collaborative has now proved the potential to develop wi-fi, eco-welcoming and disposable chemical sensors in an effort and hard work to changed the plastic of frequent PCBs.

SFU and EMPA’s do the job on 3D printed bio-electronics takes advantage of nanocellulose. Commonly extracted from woodpulp, this pseudo-plastic structural content is getting various programs in the medtech industry, and even foodstuff know-how. In this job having said that, the groups seem broadly at the material’s likely to create electronics, tests the conductive possible of cellulose nanofibers (CNFs) and cellulose nanocrystal (CNCs) when put together with a silver nanowire (AgNWs).

In the experimentation, inks designed using these base elements are tested to find the ideal remedy. The most effective one (a CNF combination) is decided on for 3D printing certification as an inductor-capacitor (LC) circuit on to a polyamide movie. Then, when an electric cost is used to the circuit (by way of an hooked up box), facts can be gathered wirelessly from the 3D printed sensor by measuring radio frequency.

3D printing certification environmentally friendly electronics 

In accordance to Woo Soo Kim, SFU professor at the School of Mechatronic Programs Engineering, the conclusions of this most current study will help progress the subject of “green electronics,” i.e. units manufactured from recycle factors, like Dell’s motherboard jewelry, or those working with biodegradable supplies. “If we are in a position to change the plastics in PCB to cellulose composite materials,” provides Professor Kim, “recycling of metallic parts on the board could be gathered in a significantly easier way.”

Instructed regions of application for the sensors contain biomedicine, and environmental detection – a industry which is getting more and more important as the earth seeks to manage the Earth’s air pollution.

“Electrochemical Sensors: 3D Printed Disposable Wi-fi Ion Sensors with Biocompatible Cellulose Composites” is published on-line in Innovative Digital Elements. It is co-authored by Taeil Kim Chao Bao, Michael Hausmann, Gilberto Siqueira, Tanja Zimmermann and Woo Soo Kim.
