Each year, 15 million mothers are caught off guard by the premature birth of their child. Preterm births are a major source of health complications in kids under five and are nearly impossible to predict, but that may all change soon thanks to the SmartDiaphragm. It’s a device that can be inserted inside a pregnant woman and sense microscopic changes that indicate that a child is on its way. Once fully developed, the device could notify women two weeks in advance on their smartphone via Bluetooth technology, thus giving doctors more options to deal with the health problems at hand.
