With a total of two patents to his name, his work leverages innovative approaches to tackle challenges in health and safety.

Latest Patents

Sen Xu's latest patents include groundbreaking inventions that utilize electromechanical resonators for detection and measurement purposes. The first patent involves the detection and measurement of mass change using an electromechanical resonator. This invention uses a change in impedance of a resonating sensor to detect or quantify mass accumulation. By monitoring the impedance at a fixed frequency near the sensor's resonance frequency, various configurations, such as quartz crystal microbalance and piezoelectric cantilever sensors, can measure mass change effectively.

The second patent focuses on detecting and measuring live pathogens through a mass detection device. In this innovative approach, extremely minute amounts of live pathogens can be rapidly identified using a piezoelectric cantilever sensor. Remarkably, a single pathogen can be detected in about 30 minutes. The device utilizes pathogen-specific antibodies immobilized on the sensor surface and exposes it to a medium that may contain the target pathogen. If present, both live and dead pathogen cells bind to the antibodies, and a pathogen discriminator differentiates between live and dead cells by measuring the mass of the live cells.
