    Apparently, 20 percent of patients who need to wear defibrillators don't actually keep them on at all times -- even if they mean the difference between life and death. So, a group of biomedical engineering students from the Johns Hopkins University designed a new type of wearable defibrillator, which is unobtrusive and comfortable unlike traditional harness designs. The undergrads' version takes on the form of a stretchable, waterproof vest fitted with sensors. Also, instead of using bulky control boxes to monitor the condition of a patient, its sensors are connected to a relatively small smartwatch-like interface.
