Indian scientists use tiny bubbles to draw plastic circuits

Post  bejoy on Tue Aug 01, 2017 2:35 am

Indian scientists have found a way to use micro-bubbles to draw complex plastic circuits with lasers, an advance that may lead to low-cost flexible electronic devices.

Solution-printed electronics is one of the fastest growing areas in the industry primarily due to its very low cost and flexibility, researchers from the Indian Institute of Science Education and Research (IISER) in Kolkata said.
It is mostly based on conducting plastics, that is doped to increase conductivity.
The process of synthesising, doping and designing circuits separately is often complex and time-consuming.
The research was published in the journal of Materials Chemistry C.

For the first time, scientists led by Ayan Banerjee and Soumyajit Roy from IISER Kolkata, have developed a simple and inexpensive technique to simultaneously synthesise and pattern conductive polymers on a glass surface in a matter of minutes.
They exposed a solution of charged metal oxide, known as soft oxometalate (SOM) and organic molecules in a glass chamber to optical tweezers - a tightly focused laser.
