Close A new design for ultra-efficient, nano-thin piezoelectric materials could revolutionize self-powered electronics, such as wearable gadgets and medical implants like pacemakers. Researchers from the RMIT University in Melbourne, Australia, have fabricated a flexible and printable energy source material, which generates a voltage difference when pressure is applied to its surface. It could pave the way for self-powering wearables or pacemakers that could be powered by heartbeats. Details of the new nano-thin piezoelectric material are reported in the journal Materials Today, January 18.
