The sensor that detects the signs of breathing and air

New York, May 21: Researchers have developed a sensor that detects the symptoms of the disease in the air or in the toxins and informs levels of illness. An organic plastic small and thin square, the tech is immediately based on portable and disposable sensor devices, said the team from the University of Illinois at Urbana-Champaign. In a study published in the journal Advanced Functional Materials, the team led by Ying Diao demonstrated the supervision of ammonia in breathing, a symbol of kidney failure.

"In the clinical setting, physicians use bulky instruments, basically the size of a big table, to detect and analyse these compounds. We want to hand out a cheap sensor chip to patients so they can use it and throw it away," said Diao. "We developed this method to directly print tiny pores into the device itself so we can expose these highly reactive sites. By doing so, we increased the reactivity by ten times and can sense down to one part per billion," Diao added. The group works to make sensors with multiple functions to obtain more complete picture of patient health.
