This New "Smart Diaper" Sends Alerts To Your Phone When Babies Need Changing

By -

 


Parents will soon know when a diaper needs to be changed — before all the crying starts.

Scientists from Penn State University have created a smartdiaper — a nappy with a built-in sensor that will send an alert to a phone once it gets wet.

Researchers embedded four of the sensors between the layers of a diaper in order to create the “smart diaper,” as detailed in the journal Nano Letters.

Once the diaper gets wet, the graphite reacts with the liquid and sodium chloride and, as it’s absorbed by the paper, electrons will flow to the graphite to set off a sensor.

The sensor will send a message to a phone, alerting the person that the baby’s diaper needs to be changed.

Would you use them on your kid?

  The Trump administration deported eight migrants from Djibouti to South Sudan on Friday, following a series of fast-moving legal battles and despite warnings from their attorneys that they face the risk of torture, imprisonment, or even death. The deportation went ahead after a federal judge in Massachusetts denied an emergency request by the migrants' lawyers to block their removal. U.S. District Judge Brian E. Murphy wrote that a recent Supreme Court ruling allowing the deportations to proceed was “binding” and that the legal arguments before him were “substantially similar” to those already decided. A spokesperson for the Department of Homeland Security praised the decision, stating on social media, “Law and order prevails,” and described the migrants as “barbaric criminals.” The administration had previously blamed “activist judges” for delays in carrying out the deportations. Legal Challenges and Human Rights Concerns The eight migrants, detained in Djibouti for weeks, i...
