Emory University and Georgia Institute of Technology researchers are using a $2.46 million grant to test and continue developing a wearable BioPatch for farmworkers and others who work outside, funded by the National Institute of Environmental Health Sciences. This BioPatch will use multiple sensors to predict heat-related illnesses, dehydration, and acute kidney injury. By transmitting data to a smart phone or other device, artificial intelligence tools will provide real-time warnings to workers with the goal of reducing health risks associated with occupational heat exposure.
