Engineers at the University of California, San Diego, have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells. The device is a nano-sized optical fiber that detects forces down to 160 femtonewtons and sound levels down to -30 decibels. Applications include measuring bio-activity at the single cell level, or ultra-sensitive mini stethoscopes to monitor cellular acoustics in vivo.
