An international team of researchers (USA – Rice University, Israel) reports a method of using multiple pulsed-laser scribing to convert a wide range of substrates into laser-induced graphene (LIG). With the increased versatility of the multiple lase process, highly conductive patterns can be achieved on the surface of a diverse number of substrates in ambient atmosphere. The use of a defocus method results in multiple lases in a single pass of the laser, further simplifying the procedure. Any carbon precursor that can be converted into amorphous carbon can be converted into graphene using this multiple lase method. According to the researchers the new technique could lay the groundwork for the edible electronics capable of tracing the progression of foods from farm to table, as well as detecting harmful organisms that can cause gastric distress… read more.
