nonconductors
Objects that are nonconductors of heat, also known as insulators, include materials such as rubber, wood, plastic, and glass. These materials have a low thermal conductivity, meaning they do not easily transfer heat. As a result, they are commonly used to prevent or reduce heat transfer in various applications, such as insulation for buildings, electrical cables, and thermal containers.
material or an object that conducts heat, electricity, light, or sound. Electrical conductors contain electric charges (usually electrons) that are relatively free to move through the material; a voltage applied across the conductor therefore creates an electric current. Insulators (electrical nonconductors) contain no charges that move when subject to a voltage. Compareinsulator. See alsoresistance, superconductivity.
Halogens have 7 electrons in last orbit. They disparately want one electron to fill there last orbit. So they will simply hold the electrons tightly and as you know, for electricity to flow there should be free electrons. They will not give electrons so easily as metals do, who wants to get rid of extra electron/electrons to fill there outer orbit. If very high voltage is applied halogens may be forced to conduct electricity and Nobel gases will give up before halogens, when forced to conduct electricity.
It depends greatly on range of displacement. Are you looking at Neptune or a molecule?For the smaller realm using noncontact techniques:For highest resolution, laser interferometersThey are large, difficult to use, and very expensive.Capacitive sensors, such as those measure with nanometer resolution and micron or mm ranges. They require metallic target materials for easy/accurate measurement although nonconductors can also be sensed, but it is not usually for displacement.Eddy-Current sensors, measure displacement with submicron resolution with larger ranges than capacitive. They work with conductive targets only and their sensing characteristics are dependent on material. Sometimes this fact is used to make material sorting sensors.

all nonconductors are either nonmetal or metalloids (partial metals)

Most nonconductors have covalent bonds. One thing that complicates matters is that some materials with purely covalent bonds do conduct electricity at least to some degree.
In order to insulate electrical wiring you need to uses nonconductors such as rubber, plastics and ceramics.
Rubies are a nonconducting gem stone. Almost all crystals, stones and gemstones are nonconductors, with a few rare exceptions, such as graphite.
Most non-metals are in fact considered to be non-conductors. Some non-metals however do have the ability to conduct heat and electricity.
Ruby is mostly aluminum oxide with a bit of chromium. It has good thermal conductivity, but won't conduct electricity. A link can be found below for more information.
Conductors have a different molecular structure than wood and nonconductors do. For example, the atoms in copper allow electrons to "flow" through the protons and neutrons like a liquid. Wood, however, uses less complex molecules in its structure, such as carbon.
