The researchers at Birck Nanotechnology Center at the Discovery Park in West Lafayette created the device that is known as a microelectromechanical system (MEMS).

A study found that acoustic waves for music, especially rap, effectively recharge the device’s pressure sensor.

The professors used a number of genres of music to test the sensor, including Jazz, Blues, and Rock.

“Rap is best because it contains a lot of low frequency sound, notably the bass,” said Babak Ziaie, a Purdue University professor of electrical/computer engineering and biomedical engineering.
The acoustic waves from music or plain tones drive a vibrating device called a cantilever, which sends a charge to power the sensor.

Ziaie, who has applied for a patent for the new technology, further explained how the device actually works.

“Music within a certain range of frequencies, from 200-500 hertz, causes the cantilever to vibrate, generating electricity and storing a charge in a capacitor,” Ziaie explained.

“The music reaches the correct frequency only at certain times, for example, when there is a strong bass component,” he said. “The acoustic energy from the music can pass through body tissue, causing the cantilever to vibrate.”

Perdue hopes the device might help to treat people stricken with aneurisms or incontinence due to paralysis.

The researchers are positioning the new technology to replace existing sensors, which typically rely on batteries or inductance through coils, to send their electrical charge.

The findings are being detailed in a paper that is being presented during the IEEE MEMS conference that is taking place until February 2.

TMZ.com posted the 911 call, which was made on October 14, as Rick Ross headed to Memphis, Tennessee from Fort Lauderdale, Florida.

The rapper suffered a seizure on the plane, which was forced to turn around so he could receive the proper medical treatment.

Ross was taken to a local hospital, where he was released a short time later.

Later in the day, Rick Ross suffered from another seizure as he attempted to leave on a private jet, which was grounded in Birmingham, Alabama so the rapper could be treated.

Although pictures have surfaced of Rick Ross, the rapper has yet to make a comment on his medical condition.

His normally active Twitter account has been dormant since the first seizure, on October 14.
