This is a demonstration of the E-Pod from DAS Distribution inc.
Static electricity is the buildup of electrical charges on the surface of some object or material. This device can sense those charged objects at a great distance at a detection sensitivity as low as 500mV. Electro-static is usually created when materials are pulled apart or rubbed together. Basically, it is the imbalance between (+) positive and (-) negative particles on these objects or surfaces. Although the atoms on these surfaces are always full of charges, they become "electrified" whenever their pre-existing + and - charges are not equal. Some typical examples would be wool, plastic, or even the soles of your shoes as you walk across the carpet. This process causes positive (+) charges to collect on one material and negative (-) Charges on the other surface. An E-field can be compared to a magnetic field, except that it's electrical in nature. Another way of looking at it is that an E-field is a voltage without a current, and whenever you have pure voltage, then you will have a pure electric field with no magnetism involved.
Absolutely!
Some materials such as glass, hair, and Nylon tend to give up electrons and become positively charged. Other materials such as Polypropylene, Vinyl (PVC), Silicon, Teflon, Silicone tend to collect electrons and become negatively charged.
Materials are divided into three categories, depending on how easily they will allow charge (i.e., electrons) to flow along them. These are:
conductors - metals
insulators - rubber, wood
