User-Interactive Light Emitting Capacitor Display for Instantaneous Liquid Stimulus Visualization

Lightweight and flexible interactive display that offers tremendous benefit to simplify work task and improve human life was under intensive investigation for decades. Inorganic phosphor powder-based light emitting capacitor (LEC) lives with ambient manufacturing condition and simplest sandwich device feature received a lot of attention on exploring its potential in visualize mechanical, motion and thermal stimuli. Combined with microfluidic design concept, biomolecular interactive LEC (BIO-LEC) has been developed to facilitate the transduce of external liquid stimuli into light intensive signals. Here, a miniaturized biomolecular onsite interactive light emitting capacitor (BIOON-LEC) has been further studied with advancing in microfluidic design and using disposable batteries.
