Application Cases

Experiment Name: Research on Alternating-Current Electroluminescent Fibers

Research Direction: Smart Wearables

Experimental Content: Using conjugated electrospinning technology, coating, and wrapping methods, the silver-plated nylon yarn surface was respectively coated with a dielectric layer, a luminescent layer, and an outer electrode to prepare a coaxial structured fiber. This fiber can utilize a function generator (DG811) and a high-voltage amplifier (ATA-2081) to convert DC power into high-voltage AC power, driving the zinc sulfide:copper luminescent particles in the electroluminescent fiber's luminescent layer to achieve electron-hole recombination luminescence.

Testing Equipment: Function generator, ATA-2081 high-voltage amplifier, etc.

Experimental Procedure:

Figure 1: Photo of the Experimental Setup

First, the function generator was connected to the ATA-2081 high-voltage amplifier. Subsequently, high-voltage AC power was applied to the inner and outer electrodes of the fiber. The luminescent particles inside the fiber were driven by the AC power, producing luminescence. Alternatively, AC power was applied only to the inner electrode of the fiber. When touched by a human body, luminescence occurred at the point of contact.

Experimental Results:

The fiber emitted light under high-voltage AC power. When the output frequency was changed, the luminance of the fiber varied. At low frequencies, the fiber emitted green light; at high frequencies, it emitted blue light. The maximum luminance of the fiber reached 366 cd/m², meeting the lighting needs in dark environments.
