Drift Reduction in 2D PtSe2 Piezoresistive Pressure Sensors Through an On‐Chip Wheatstone Bridge

open access: yesAdvanced Electronic Materials, EarlyView.
Drift is a major source of error affecting the accuracy and repeatability of sensors. A Wheatstone bridge (WSB) enables high sensitivity, accuracy, and the elimination of common‐mode drift. We apply the WSB concept to highly sensitive piezoresistive pressure sensors made with two‐dimensional layered platinum diselenide transducers.
