Tiny wireless sensors could revolutionize how premature babies are monitored Tiny wireless skin sensors are being tested to monitor stroke recovery and breathing disorders, but they could also help babies who are born prematurely, according to a new study in the journal Science. The skin-like silicon patches attach to the chest and foot proved just as reliable as traditional electrodes for tracking babies' heart and respiration rates, temperature, blood pressure and blood-oxygen level.
