JUNE 1ST, 2023 CONN HASTINGS CARDIOLOGY, DIAGNOSTICS, MATERIALS Researchers at Penn State have developed a low-cost, wearable sensor using pencil-on-paper technology. This approach involves depositing graphite (pencil ‘lead’) on paper that has been treated with sodium chloride, to create a conductive, low-cost sensor. Previously, these researchers had developed such sensors to detect moisture and even used...
