ACCIS CDT paper featured by the American Institute of Physics

22 June 2018

An article authored by Rujie Sun, an EPSRC Centre for Doctoral Training in Advanced Composites for Innovation and Science (ACCIS CDT) student, has been published in the prestigious Applied Physics Letters journal of the American Institute of Physics (AIP).

The paper on Kirigami stretchable strain sensors with enhanced piezoelectricity induced by topological electrodes has also been showcased in the Scilight magazine of the Institute.

The work describes a new class of stretchable piezoelectric sensor for biomedical applications created using Japanese Kirigami and Chinese paper cutting patterns, coupled with new electrodes designs. This new type of sensor generates voltage outputs 2.6 higher than analogous configurations currently available.

Rujie said: "I am very happy with this work. In my activities, I merge multifunctional material properties with topology to create new classes of sensors and actuators, and this sensor is a good example. I’m working on other designs and applications based on Kirigami principles, and I am looking forward to presenting those to the scientific community."

Professor Fabrizio Scarpa, Rujie’s primary supervisor, said: "Rujie and co-workers have designed a very original and efficient sensor to measure strains in soft tissues. The way Rujie has coupled together Kirigami design principles and electrodes topology to avoid charge cancellation is brilliant."
