Infrared energy refers to one part of the electromagnetic spectrum. The spectrum contains a wide variety of wavelengths from high frequency gamma rays and x-rays to low frequency TV signals and radio waves. Infrared energy rests in the middle of this spectrum, toward the low end of the visible part of the continuum.

New Developments in Infrared Technology

In general, infrared energy is associated with heat, although the wavelengths share many of the properties of higher frequency light energy fields. What this means is that infrared energy can bend and retract light. This property makes it an important part of night vision technology. Infrared energy is used in the motion tracking devices employed in a host of security and military equipment.

Infrared energy is also evident in the human body. Research has found that our bodies use this form of energy for a variety of normative processes including warmth, restoration, and healing. Indeed, throughout the day, we are burning, expending, and dispersing energy.

Given that infrared energy is a low-level energy source and that it is relatively harmless to humans, researchers are investigating additional technological uses it may have. Although such work is relatively new, it holds great promise for producing safe alternative energy sources. Specifically, infrared energy sources may be used to power cellular phones, pagers, and other devices without harmful side effects for humans. This would provide a viable alternative to the low-level radiation currently used in cellular technology.
