A new kirigami-inspired engineering technique allows scientists to create a range of folding, twisting and bending materials
Northwestern University
There is a lot engineers can learn from Japanese paper folding art forms, from cheap batteries made from paper and water to tiny robots that are activated by heat. While origami gets a lot of the attention, a variation of this called kirigami also has plenty to offer. A team of scientists has taken this technique down to the nanoscale for the first time, a breakthrough they say opens up new possibilities in applications ranging from robotics to aerospace.
