Inspiration from the natural world: Boosting flexible electronics
With increased study of bio-adhesives, a significant effort has been made in search for novel adhesives that will combine reversibility, repeated usage, stronger bonds and faster bonding time, non-toxic, and more importantly be effective in wet and other extreme conditions.
A team of Korean scientists?made up of scientists from Korea Institute of Science and Technology (KIST) and UNIST?has recently found a way to make building flexible pressure sensors easier—by mimicking the suction cups on octopus’s tentacles.
In their paper published in the current edition of Advanced Materials, the research team describes how they studied the structure and adhesive mechanism of octopus suckers and then used what they learned to develop a new type of suction based adhesive material.
According to the research team, “Although flexible pressure sensors might give future prosthetics and robots a better sense of touch, building them requires a lot of laborious transferring of nano- and microribbons of inorganic semiconductor materials onto polymer sheets.”
The Korea Institute of Science and Technology (KIST) is a multi-disciplinary research institute located in Seoul, South Korea.
Founded in 1966, it was the first multi-disciplinary scientific research institute in Korea and has contributed significantly to the economic development of the country, particularly during the years of accelerated growth in the 1970s and 1980s. It has a research staff of over 1,800 research scientists, visiting scientists, fellows and trainees, and foreign scientists involved in basic research in various fields of science and technology.
There are two research institutes and two research divisions at KIST including the Brain Science Institute, the Biomedical Research Institute, the Future Convergence Research Division, and the National Agenda Research Division.
