Title: Innovations by Inventor Xiaojun Tong: Pioneering Acoustic Sensor Technologies
Introduction: Xiaojun Tong is a distinguished inventor based in Wuxi, China, known for his significant contributions to the field of sensor technology. With a total of two patents to his name, his work primarily focuses on thin film bulk acoustic wave sensors, which hold great potential in various applications.
Latest Patents: Xiaojun Tong's latest patents include advanced innovations in thin film bulk acoustic wave sensor technology. One of his notable patents, the Thin Film Bulk Acoustic Wave Sensor Suite (T-BASS), presents a suite of sensors featuring coatings of biological and chemical materials. These sensors employ multiple electrode depositions and a piezo-active thin film transducer layer, all hosted on a substrate. The T-BASS technology generates a low-voltage, integrated circuit (IC)-compliant thickness-directed electric field, ensuring uniformity over a substantial portion of the active area of the bulk acoustic wave (BAW) structure. These BAWs are designed to propagate as essentially extensional plane waves away from the substrate surface, offering enhanced performance for sensing applications.
Another innovative patent from Tong focuses on Lateral Field Excitation of Bulk Acoustic Waves using an Interdigital Bulk Acoustic-Wave Transducer (IBAT) device. This device features pairs of exciting electrode fingers on a piezoelectric substrate, generating an IC-compatible voltage at high electric field strength. The resultant lateral electric field is designed to achieve uniformity across a significant portion of the active BAW structure area, significantly minimizing sharp voltage spikes that can occur at low voltages on integrated circuits. This robust configuration also allows for creating various IBAT structural arrangements through dielectric over-coating, enhancing the versatility of the devices.
