Bass-thumpin’ rap music used to power implantable medical sensor

We've been following the evolution of patient-embedded medical sensors for some time - miniature devices that run on batteries, transcutaneous (through-the-skin) induced current, even sugar and provide constant monitoring of various metabolic parameters. Now, a team from Purdue University's Birck Nanotechnology Center has developed a prototype pressure sensor which promises to address the shortcomings of previous designs and utilizes a novel power supply: the acoustic energy from bass-heavy riffs of rap music.
