Researchers have designed a robotic “artificial skin” that is as unique as the team’s animal inspiration—the platypus. Created by collaborators between China’s Tsinghua University and the Beijing Institute of Nanoenergy and Nanosystems, the dual-sensory system can interpret information not just from direct physical touch, but also through detecting electrostatic changes in the air around it.

Although I’m sharing the Popular Science article for easier reading, I’d recommend checking out the journal article it cites, as it gets into the details of the research. Best of all? Journal article’s open access, so from what I can tell by checking between browsers, it’s not paywalled!
