Scientists at La Trobe University have produced a new, powerful electricity-conducting material in research which could revolutionize smartphones and wearable technologies like medical devices.

The new technique uses hyaluronic acid, well known due to its popularity in skincare, applied directly to a gold-plated surface to create a thinner, more durable film, or polymer, used to conduct electricity in devices like biosensors.

Lead researcher Associate Professor Wren Greene said the technique could lead to major improvements in the function, cost and usability of devices like touchscreens and wearable biosensors.
