Abstract
In embodiments of a passive stylus with RFID-enabled sensing, a computing device includes a touchscreen that senses touch contact, and includes an RFID interrogator to interrogate passive RFID tags. The stylus includes a conductive tip designed for interaction with the touchscreen of the computing device. The stylus integrates a pressure sensor that senses pressure when the conductive tip of the stylus contacts the touchscreen. The stylus also includes at least one RFID antenna that is positioned in a body of the stylus to prevent detuning the RFID antenna when the stylus is held for use. The passive RFID tag can receive pressure sensor data from the pressure sensor in the stylus, and the passive RID tag can be read by the RFID interrogator to determine the pressure applied to the conductive tip of the stylus in order determine whether the stylus is contacting the touchscreen or only hovering above it.
