Researchers at Purdue University have developed a new type of implantable pressure sensor, which is powered by acoustic vibrations such as those that come from music,and particularly rap music, due to it’s heavy driving bass beats.
In hopes of treating people affected by aneurisms, incontinence due to paralysis, researchers at the Purdue University have developed a new medical sensor in the form of a vibrating cantilever which is activated by frequencies in the range of 200-500 hertz. Frequencies in this range cause the cantilever to vibrate, creating energy which is then stored in a capacitor for later use.
“The music reaches the correct frequency only at certain times, for example, when there is a strong bass component,” Babak Ziaie, a Purdue University professor of electrical & computer bioengineering and biomedical engineering, explains “The acoustic energy from the music can pass through body tissue, causing the cantilever to vibrate.”
