Amorphous FeZr metal for multi-functional sensor in electronic skin

Abstract

Flexible metal for Electronic Skin Amorphous alloys have never been such a viable approach for flexible electronics because now their excellent properties are not compromised by the structure and morphology. A collaborative team of scientists led by Prof Sanghun Jeon from Korea Advanced Institute of Science and Technology optimize the performance of a Fe33Zr67 metal alloy for multifunctional skin-like sensors. One critical step is that they understand and control the deposition condition to avoid the porous structure and obtain uniform amorphous alloy films. As a result, the Fe33Zr67 metal alloy possesses higher strength, lower Young's modulus and can be made into pressure sensors, temperature sensors and photosensors when integrated with In-Zn-O thin film transistors. This highly versatile and high performance alloy can be used in many scenarios, such as medical, healthcare and wearable electronics.
