If robots could detect human emotions, it might make them more “human.” That’s the premise of new research by Korean scientists, who have developed simple, low-cost, ultra-sensitive wearable strain sensors that can detect facial expressions.
This kind if detection is normally done with vision sensors connected to a computer, with facial-analysis algorithms, but such systems are expensive and have low mobility and high complexity, the researchers note in a paper published in ACS Nano.
