Researchers at the University of Hawaiʻi at Mānoa College of Engineering say they developed a 3D-printed, wearable sweat sensor.Called the “sweatainer,” the device harnesses the power of additive manufacturing to enable a new type of wearable sweat sensor. The researchers say the small, wearable device — similar in size to a child’s sticker — expands the capabilities of wearable sweat devices. Using various sensors, the device collects and analyzes sweat to enable health monitoring.
“3D-printing enables an entirely new design mode for wearable sweat sensors by allowing us to create fluidic networks and features with unprecedented complexity,” Department of Mechanical Engineering Assistant Professor Tyler Ray said. “With the sweatainer, we are utilizing 3D-printing to showc…
