lighting

– The article discusses a tattoo light that can easily be moved and adjusted.
– The light features two rotating joints on the light arm and halo, allowing for a 360掳 range of light.
– The design of the light is curved to provide full-coverage, shadowless light.
– The light has three different tones: Cool, Daylight, and Warm.
– The tri-tone LEDs were designed to provide bright light without generating heat.
– The light also includes a custom diffuser shield to minimize glaring.
– A light-emitting diode (LED) tattoo is a body modification that involves implanting technologically based materials into the skin instead of traditional ink.
– LED tattoos are still in the development stage, with potential applications in the medical, commercial, and personal domains.
– Current LED tattoo devices are limited by their isolation from the body and reliance on gold and titanium for electrical connections.
– Researchers are working on developing biodegradable contacts to eliminate unnecessary materials.
– LED tattoos have been successfully implanted on mice without harm.
– Research on silicon-silk technology is being conducted at the University of Pennsylvania’s Engineering Department, with commercial interest from Royal Philips Electronics.
– Future LED tattoos may use silicon chips that are around the length of a small grain of rice.
– The chips are placed on thin films of silk, which conform to biological tissue with the help of saline solution.
– The silk dissolves over time, leaving the thin silicon circuits in place.
– While silicon has not been proven to be biocompatible, it has been used safely in other medical implant operations.
– LED tattoos would not interfere with normal physiological processes.
– LED technology has been approved by the U.S. Food and Drug Administration, but LED tattoos are still undergoing development.
– One potential medical application of LED tattoos is using silk-silicon LEDs for blood-sugar readings.
