About awarded research
Daisuke Kobuchi, Romain Siragusa, Yoshiaki Narusue, Arnaud Vena, and Etienne Perret, “Contactless Switching of a RF CBRAM Switch,” URSI General Assembly and Scientific Symposium (URSI GASS 2023), Sapporo, Japan, Aug. 2023.
Chipless RFID technology has been explored as a solution to low-cost individual identification systems. The CBRAM switch, a type of non-volatile switch, has been proposed as a means to embed information in chipless RFID tags. However, switching CBRAM requires direct contact between the probes and the switch electrodes for applying a DC voltage. This direct-contact method potentially causes short-circuiting of the tag antenna and degradation of switch electrodes. To address these challenges, we propose using a writer coil to induce multiple pulse voltages in the tag antenna, thereby switching the CBRAM switches without direct contact. We experimentally confirm the effectiveness of the proposed switching operation.
