Nature-inspired self-sensing materials could lead to new developments in engineering

Posted by in categories: engineering, health, nanotechnology

The cellular forms of natural materials are the inspiration behind a new lightweight, 3D printed smart architected material developed by an international team of engineers.

The team, led by engineers from the University of Glasgow, mixed a common form of industrial plastic with carbon nanotubes to create a material which is tougher, stronger and smarter than comparable conventional materials.

The nanotubes also allow the otherwise nonconductive plastic to carry an throughout its structure. When the structure is subjected to mechanical loads, its electrical resistance changes. This phenomenon, known as piezoresitivity, gives the material the ability to “sense” its structural health.
