Carmel Majidi’s career mission is to discover materials, hardware architectures, and fabrication methods that allow robots and machines to behave like soft biological organisms, and be safe for contact with humans. The aim is to replace the bulky and rigid hardware in existing robots with soft, lightweight, and deformable technologies that match the functionality of natural biological tissue. Currently, his group is focused on filled-elastomer composites and soft microfluidic systems that exhibit unique combinations of mechanical, electrical, and thermal properties and can function as “artificial” skin, nervous tissue, and muscle for soft robotics and wearables. He’s particularly interested in approaches that are practical from a rapid prototyping and robotics implementation perspective. This includes efforts to enable robust mechanical and electrical interfacing between soft-matter systems and conventional microelectronics and hardware.

Majidi discusses electronic tattoos

MechE’s Carmel Majidi spoke with The Economic Times about the electronic tattoos he has developed in his lab that could power the future’s wearable devices. “We…coat the particles with a thin layer of gallium indium alloy that increases the electrical conductivity and allows the printed circuit to be more mechanically robust. The tattoos are ultrathin, very stretchable, and inexpensive to produce,” said Majidi.
