A CNU research team developed an ultra-high sensitivity sensor conceived from a spider’s ankle.

The research team of Professor Lee Dong-won (School of Mechanical Engineering) succeeded in developing an extremely small-sized (2㎜ in width, 6㎜ in length, and 120㎛ thick) high-sensitivity sensor. The research was motivated by the tiny crack in the spider's ankle, which serves to detect minor tremors that appear when the spider web catches prey.

The findings of the research were published on January 27 in Nature Communications (Impact Factor: 11.88), Nature's sister magazine.

Researchers proved that it is easy to identify changes in resistance and repetition of contraction and relaxation if cardiomyocytes are cultured on this sensor.

The research results enable stable and long-term applications in a variety of solution environments, such as a culture medium, while maintaining the sensitivity of the existing crack sensor. It is also expected to be used as a fundamental research for the development of various applied technologies.
