    Flexible electronic devices should lead to new practical applications. Parallel arrays of inorganic nanowires have now been integrated into a flexible pressure-sensor array on a macroscopic scale. The sensor array operates at low voltage and acts as an artificial electronic skin, sensing pressure profiles with high spatial resolution.

    Resistive nanowire arrays are intensively pursued as easy-to-fabricate memory technology, where data can be written and read through simple voltage–current operations. However, problems encountered in achieving stable switching independent of external influences has hampered their progress. The complementary, antiserial arrangement of two memory elements is now shown to lead to the desired stability.

    The origin of the effect that a magnetic field has on various electronic properties of organic semiconductors is still controversial. It is now shown that substituting hydrogen for deuterium in conducting polymers changes the response to a magnetic field substantially, proving the essential part played by hyperfine interaction in this effect.

    Creating p–n junctions using semiconducting polymers has proved to be challenging because of difficulties in depositing semiconducting polymer films. Now, by using a cationic conjugated-polymer electrolyte and a neutral conjugated-polymer layer, devices with a fixed bilayer organic p–n junction and fast response times have been fabricated.
