Researchers from the University of Chicago have found an easy, inexpensive, and scalable method for fabricating bioelectronics components using lasers. The technology has potential for use in medical applications, such as in pacemakers.
The process begins with a compound called polydimethylsiloxane, or PDMS, which is a type of elastomer — a very elastic, stretchable material. Using an inexpensive commercial laser cutter, the researchers transformed the PDMS into a dense silicon carbide layer, a material useful for electronics and, particularly, bioelectronics.
Previously, the components had to be synthesized separately and then molded together. This process allows sections of the soft PDMS to be turned directly into…READ MORE
