A joint group of specialists from Canada’s Simon Fraser University and the Swiss Federal Laboratories for Materials Science are creating 3D printable IoT sensors which are dispensable and environmentally friendly. Driven by SFU professor Woo Soo Kim, the exploration is researching the utilization of wood-inferred cellulose materials for electronics.
Commonly, electronics use polymer materials as their base, which are viable however shockingly not feasible. This is the reason Woo Soo Kim and his group are investigating the utilization of 3D printed cellulose as a potential substitution, as it tends to be discarded with far less of an effect on environment. The 3D printed sensors can likewise be tuned for adaptability and implanted into an assortment of bigger structures, including 3D shapes and textiles.
The forward-thinking project, “Electrochemical Sensors: 3D Printed Disposable Wireless Ion Sensors with Biocompatible Cellulose Composites,” was as of late shrouded in the journal Advanced Electronic Materials and is being done at PowerTech Labs in Surrey, British Columbia—a facility which allegedly houses a scope of cutting edge additive manufacturing technologies.
“Our eco-friendly 3D printed cellulose sensors can wirelessly transmit data during their life, and then can be disposed without concern of environmental contamination,” elaborated Kim, a professor in the School of Mechatronic Systems Engineering at SFU. “This development will help to advance green electronics. For example, the waste from printed circuit boards is a hazardous source of contamination to the environment. If we are able to change the plastics in PCB to cellulose composite materials, recycling of metal components on the board could be collected in a much easier way.”
Professor Kim is additionally working with another group of specialists from South Korea’s Daegu Gyeongbuk Institute of Science and Technology’s (DGIST’s) department of Robotics Engineering and tech organization PROTEM Co Inc. This exploration exertion—separate from the 3D printed electronics yet which apparently could be utilized couple with it—is centered around the improvement of printable conductive inks for electronics.
As of late, this project made a significant step ahead with the advancement of embossing procedure that is able to do unreservedly engraving fine circuit designs onto an adaptable polymer substrate. The strategy could affect processes for semiconductors, wearable devices and displays.
