Abstract: Disclosed is an improved pressure touch sensing method and device that can sense touch and pressure using a plurality of conductive pads having the same properties and not requiring separate machining processes and special materials instead of a pressure sensor and a touch sensor having different properties and can detect environmental effects without a separate sensor to prevent malfunction due to change in environment (temperature/humidity), and can reduce manufacturing costs.
