A voltage detecting glove comprises a glove liner and an outer glove shell. A conductive antenna is disposed inside the outer glove shell but separated from the glove liner by a buffer. The antenna is connected to electronic circuitry configured to sense a voltage indicative of the proximity of the antenna to an AC electric field resulting from energized AC source, and to activate an alarm if the strength of the field exceeds a preselected threshold limit.

Voltage detecting glove

A method is provided that produces nanocomposite materials containing well-dispersed, nanoparticles encapsulated in a polymer matrix. A feedstock comprising a colloidal dispersion of nanoparticles in a solvent and a polymer dissolved in the same solvent is passed through an ultrasonic nozzle using a flow control device, producing an aerosol of drops having diameters less than about 100 micrometers. The aerosol of drops is then mixed with a fluid that is miscible with the solvent, is a nonsolvent for the polymer, and destabilizes the colloidal dispersion. As a result, well-dispersed polymer-encapsulated nanoparticles precipitate. The method operates at atmospheric temperature and pressure and allows for independent control of the precipitation of the particle and of the polymer.
