Leaf skeletons inspire smarter sensors

Researchers at the University of Turku, Finland, have developed a new method to enhance the flexibility of electronics by replicating the fractal patterns found in leaf skeletons. These natural structures, renowned for their hierarchical, self-replicating designs, were utilised as templates to create biomimetic surfaces with an accuracy of over 90 per cent.

By coating dried leaf skeletons with durable polymers, the team produced flexible, breathable, and highly conductive materials suited for wearable sensors, electronic skin, and prosthetics. A robotic hand fitted with the material successfully detected touch through an integrated pressure sensor.
