Stretch faux leather 3D printed

Chemical engineer Zhenan Bao and her Stanford research team in a new study revealed how

they printed a stretchable but reusable integrated circuit on rubber materials.

There are more than 40,000 transistors on one square centimeter of artificial leather: the team plans to increase this number.

It is planned to increase the number of transistors to a billion, this will be enough to create simple circuits for sensors on the skin, as well as implantable bioelectronics.

Our method increases the density of elastic transistors by more than 100 times over earlier designs. We have achieved this without sacrificing either electronic or mechanical performance.

The authors explain that while working, theyused a new process to create flexible circuits: they stretched them parallel and perpendicular to twice their original size. As a result, they did not crack or delaminate. The transistors remained electrically stable even after thousands of repeated stretches.
