By carefully placing nanostructures on a flat surface, researchers at LiU have significantly improved the performance of so-called optical metasurfaces in conductive plastics. This is a major step for controllable flat optics.

We develop and study novel concepts based on the combination of unique features provided by conducting polymers and the exceptional light-matter interaction of plasmonic metal nanostructures.

Researchers at LiU have shown that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves.

It may in the future be possible to harvest energy with leaves fluttering in the wind. Researchers at the Laboratory of Organic Electronics have developed a material that generate an electrical impulse when light fluctuates from sunshine to shade.

Inspired by the behaviour of natural skin, researchers at the Laboratory of Organic Electronics have developed a sensor for use with electronic skin. It can measure changes in body temperature, and react to both sunlight and warm touch.

Researchers at LiU have developed optical nanoantennas that can be turned on/off and gradually tuned by applying electrical potentials. The study opens for applications including dynamic flat metaoptics and tuneable smart materials.

Researchers at the Laboratory of Organic Electronics have developed optical nanoantennas made from a conducting polymer. The antennas can be switched on and off, and will make possible a completely new type of controllable nano-optical components.

Researchers at LiU have now shown that electrical tuning of passive radiative cooling can be used to control temperatures of a material at ambient temperatures and air pressure. The results have been published in Cell Reports Physical Science.

Researchers at Linköping University have developed a method that may lead to new types of displays based on structural colours. The discovery opens the way to cheap and energy-efficient colour displays and electronic labels.
