Simultaneous sensing, visualizing and memorizing magnetic field provide a useful platform to obtain information that human is rarely sensible. Here, we present a single-level magnetoactive electroluminescent display (MED) capable of sensing, visualizing, and memorizing the magnetic field. Our MED is successfully developed by employing a magnetoactive conductive fluid into an alternating current (AC) electroluminescent (EL) display consisting of an AC field responsive emissive layer with two parallel electrodes. The luminance intensity depends upon the degree of percolation network of the magnetoactive fluid. More importantly, the information of magnetic field is readily stored due to collective fixation of the channel with the networked carbon nanotubes. Furthermore, by constructing flexible arrays of MEDs, we are able to realize a pixelated EL display mounted on skin where a variety of static and dynamic information of magnetic field is simultaneously detected, visualized and stored. |
