A novel technological way to decorate you for the festivities!

With recent advances in semiconductor technology, the maximum luminous intensity of red l.e.d.s has increased to several candelas. Now consider that human flesh is translucent to red light. Combine these two facts, and we have the basis for the present project.

The average human cheek has a thickness between one and two centimeters, and this makes it possible to “backlight” a cheek from the gums with a high intensity l.e.d., causing it to glow in the subdued light of a Christmas party or disco etc.

The slim-line circuit featured here is slipped between the gums and cheek, and is activated by the presence of saliva. Afterwards, when it is removed and cleaned-up, its current consumption drops to practically zero. Therefore, the circuit could likely be used for years in a row without battery replacement.
