Electronics is moving away from a one-solution-fits-all approach based on traditional semiconductor technologies. This is because an ecosystem for biocompatible, large-area, environmentally friendly, wearable, and high-performance electronics based on a variety of materials and technologies can provide bespoke solutions for specific application scenarios. An important aspect of this development is represented by soft and flexible systems that can bend and stretch. Here we present our flexible electronics technology which is based on thin films and oxide semiconductors. Transistors, sensors and circuits fabricated on polymer substrates exhibit carrier mobilities around 16.5 cm2 V-1 S-1, transit frequencies exceeding 100 MHz, and voltage gains up to 19 dB while being bend to millimeter radii or stretched by more than 200%.

Abstract
Electronics is moving away from a one-solution-fits-all approach based on traditional semiconductor technologies. This is because an ecosystem for biocompatible, large-area, environmentally friendly, wearable, and high-performance electronics based on a variety of materials and technologies can provide bespoke solutions for specific application scenarios. An important aspect of this development is represented by soft and flexible systems that can bend and stretch. Here we present our flexible electronics technology which is based on thin films and oxide semiconductors. Transistors, sensors and circuits fabricated on polymer substrates exhibit carrier mobilities around 16.5 cm2 V-1 S-1, transit frequencies exceeding 100 MHz, and voltage gains up to 19 dB while being bend to millimeter radii or stretched by more than 200%.
