Tohoku Univ. Technology : “Black body” with nano-micro size metal protuberance and its manufacturing method : T12-022
Capable of absorbing more than 95% of “ultraviolet” to “visible” to “infrared” light!
“Black bodies” are substances that can completely absorb all kinds of light, and carbon nanotube (CNT) black bodies are known as substances that can almost completely absorb light. CNT black bodies can absorb more than 98% of light (electromagnetic waves) in a wide wavelength range of 200 nm-200μm from “ultraviolet” to “visible” to “far-infrared” light. CNT black bodies can be used for shielding cameras and optical equipment, infrared absorbers, thermal infrared sensors, and cooling electronic equipment. However, CNT black bodies are fine powders, and there have been some problems such as difficulties in manufacturing and handling them. This invention provides a nano-micro metal “black body” capable of absorbing light over a wide wavelength range from “ultraviolet” to “visible” to “infrared” light, and capable of selectively adjusting the absorption direction of light.

Company information
The revenue generated from technology transfer is reinvested as new research funding for universities and researchers, and is utilized to create further research outcomes. To ensure the smooth operation of this cycle, known as the "Intellectual Creation Cycle," we will vigorously promote technology transfer. The types of seeds we handle include patents, know-how, databases, and programs. We have established a collaborative framework by signing basic technology transfer agreements with the following universities (as of June 1, 2025): Tohoku University, Hirosaki University, Iwate University, Akita University, Fukushima University, Yamagata University, Tohoku Gakuin University, Iwate Medical University, Fukushima Medical University, Aizu University, Miyagi University, Hokkaido University, Muroran Institute of Technology, and Showa Medical University.
