Intelligent Multimodal Sensors Based on Novel Electronic-Ionic Bi2O2Se Semiconductors

In light of the data surge during the Internet of Things (IoT) era, we have been developing intelligent multi-modal sensors based on the novel 2D electronic-ionic Bi 2 O 2 Se semiconductors to in-situ detect and process information in more accuracy and efficient ways. We scrutinized the physical mechanisms of multi-dimensional carrier transport within Bi 2 O 2 Se interlayers. Then we successfully fabricated high-performance thermal-bolometric multi-mode sensors tailored for intelligent sensing. Moreover, we developed an advanced signaling processing method to distinguish multi-modal outputs. We also rationally designed logic-in-sensor devices for both single-modal and multi-modal applications.
