The healing power of rap
7 Healthcast: The healing power of rap
A breakthrough is happening at Purdue University.
Researchers are using music to not only keep you healthy, but save lives.
At Purdue University, a sensor is placed inside a water balloon, which simulates the soft tissue of the body, like the bladder or brain.
Grad student Albert Kim bombards the balloon with the music of rapper J. Cole.
It's all about helping people with concussions, bladder problems, or weak spots in blood vessels.
The Purdue-developed sensors could be implanted to alert doctors to sudden, dangerous changes in pressure. But there are some hurdles.
"Power has always been a problem for us. How to provide power to such microsystems," said Professor Babak Ziaiwe.
Batteries are too big, magnets too weak.
He needed something everyone has, even at home.
"Of course, music is one thing," Ziaiwe said.
They found the bass in J. Cole's song made a little tail inside the sensor vibrate.
That produced the power needed to measure fluid pressure and send the data to a monitor doctors can read.
"The frequency of that pulse is an indication of pressure," Ziaiwe said.
But what if the patient can't stand rap music?
They just need to change the size of the sensor's tail, to pick up the frequencies of other forms of music.
The next step is to test the devices in pigs.
