Abstract
Disclosed herein are techniques for generating an image of a target object using a sensor. The sensor includes a substrate and a single transceiver. The transceiver includes a first electrode, a second electrode, and a layer of electrical material positioned between the two electrodes. The transceiver also includes a control unit configured to switch the transceiver into a transmit mode or a receive mode. The transceiver further includes a receiving circuit configured to receive, store, and output a detection signal caused by an interaction between the sensor and the target object. The second electrode, the control unit, and the receiving circuit can be formed on the substrate.
