Wearable sweat sensors

This new is from a page named Livescience where it talks about the innovations of the technology. This new was written the 27 of january of 2016 by Charles Q. Choi.

In the future wearable sensors would use human sweat to look for signs of disease. Sweat is a rich source of chemical data that could help doctors determine what is happening inside the human body, scientists explained in a new study. However, they do not provide data about a user's health on a molecular level. "This could help tell athletes to take liquids or warn them they are going through heat shock," Javey told Live Science.
The invention uses five sensors to simultaneously track levels of glucose, lactate, sodium and potassium, as well as skin temperature. This data is fed to a flexible board of microchips that processes these signals and uses Bluetooth to wirelessly transmit data to a smartphone. All of these electronics could be incorporated into either a wristband or headband.
Wearable sweat monitors could track only a single molecule at a time, which could generate misleading information, the researchers said. 
The researchers have filed a patent on their work, although they are not currently collaborating with anyone to commercialize the sensors, Javey said.
I like this new invent because it's seems to be easy for  work with it and we can use it in our phone. But it also afraid me a little bit because I don't know the secondary effects, they only say the good things so I don't know. But it's obviusly that the tech is going forward every day
