Japanese scientists have created a pressure-sensitive “skin” for human fingers described as being “much thinner than a human hair.” The ultrathin nanomesh sensor was built by a team led by Sunghoon Lee at the University of Tokyo. According to information from the university, the porous membrane is so thin that, when applied to a fingertip, it doesn’t affect the sense of touch or ability to grasp objects. Test subjects reported that the durable mesh was “imperceptible.” This technology could ultimately find use in archiving the work of people who perform very delicate, exacting tasks, such as artisans or surgeons, which could lead to other people or robots learning to perform the same tasks at the same skill level. The research was published in the journal Science. Photo: 2020 Someya et al.
