Smart pajama detect why you cannot sleep smoothly!

The pajamas that you take to bed soon will be able to say the good you are sleeping. Trisha Andrew and colleagues from the University of Massachusetts, Amherst, have developed a cotton pajamas t-shirt with sensors to control breathing, heartbeat and movement. The T-shirt can be used to control the sound quality of the user, such as the amount of REM sleep they receive, which is believed to be important for consolidating memories, or if they have respiratory problems during the night. Five lightweight sensors are stitched to the jacket of the shirt.



Four sensors detect constant pressure, such as a body pressed on a bed. Fifth position on the chest detects rapid pressure changes and provides information on heart rate and breathing.

"They sew the seams of the shirt, so you do not see them," says Andrew. The shirt is totally profitable. The signals collected from the five patches are sent to a small circuit board that looks and works like a normal pajamas button. The button has an integrated Bluetooth transmitter that sends the data wirelessly to a computer for analysis. The pajamas shirt is still in its early stages: it has been tested for eight days in only eight people, and the team is still in the process of ensuring that sensors are accurate for different shapes and heights of the body. Andrew says the shirt can not yet be used to diagnose medical problems, but the goal is to eventually replace sound studies in the laboratory where participants connect to various machines at night. Instead of that, they could simply put the top of the pajamas. The team is still in the process of ensuring that the sensors are accurate for various forms of body. So far, they tried the shirt with 35 people. They are now developing a complete set of pajamas that includes trousers with integrated pressure detectors that detect the amount of tension in the .back. The team has presented the work at a meeting of the American Chemical Society this week
