Amazing spider leg inspires super-sensitive 'hearing' device

Talk about spidey senses! Inspired by slit-like organs in the wandering spider's leg joints, scientists have built a super-sensitive device that can detect sounds and subtle mechanical vibrations. This spider-like sensor, described in the journal Nature, could be used for a range of applications, from detecting dangerous amounts of strain on a structure to picking up speech patterns in a noisy room. The wandering spider, known as Cupiennius salei, has hairy reddish legs and packs a nasty toxic venom. Females and males communicate in part using vibrations. For example, if a female rubs her mouth and abdomen against a banana leaf, amorous males must be able to sense the leaf’s...
