Now, Sensor to Monitor Blood Sugar From Sweat

Scientists in Australia have developed a new sponge-like copper based material for wearable sensors that can measure blood sugar levels from sweat. People with diabetes often have low levels of insulin, a hormone that converts sugars to energy, which means they have to closely watch their glucose or blood sugar levels to prevent further chronic health complications. According to researchers the structure can also accurately detect glucose in body fluids other than blood, such as sweat or tears. Researcher said glucose sensors based on copper have good conductivity and low cost. “The sponge like porous structure greatly increases surface are, enhancing the sensitivity required to trigger an electrochemical signal.
