How can I be invisible to infrared?

A bendable sheet of silicon can hide 95 percent of infrared light, rendering objects essentially invisible to heat-sensing night vision goggles or infrared cameras. Black silicon is made by growing silicon crystals at various heights on a silicon wafer, creating what looks like a dense forest of needles.

Does infrared work in daylight?

Thermal imaging cameras contain a special lens which focuses the heat, or infrared energy which is given off by an object onto a detector which is sensitive to heat. So, being that it is unaffected by light, thermal imaging will work just as well in daylight as in complete darkness.

What can block infrared cameras?

Any electrically conductive material will block infrared radiation. The greater the conductivity, the greater the blocking. ​Food wrapped in aluminum foil. Since aluminium foil is a highly conductive material, it will kill all infrared radiation.
