The pressure that makes conductivity higher: new record in the ICN2
Researchers from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) the Barcelona synchrotron Park (BSP) works with, have measured, at room temperature, the highest values of piezoresistivity ever detected in an electroceramic material, overcoming the registers for materials such as silicon nanowires or graphene. Moreover, it was measured with a simple technique that avoids using complex equipment to control pressure.

The research has been conducted by Oxide Nanoelectronics Group, led by Prof ICREA Gustau Catalan. Dr Neus Domingo is the first signer of the article published in Nanoscale and her intervention has been essential for the development of the research.

Piezoresistivity happens when certain materials change their electric conductivity once submitted to a pressure deforming them.

In other words, when the material is pressed, there is better electricity conduction. This fact leads to a wide range of possible applications, from pressure sensors to microelectronic transistors where the current is controlled by pressure instead of voltage.
