Demonstration of Real-Time Data Acquisition in CMOS Capacitive Sensor Arrays: Evaporation Monitoring

This video demonstrates the real-time data acquisition and noise reduction capabilities of a CMOS capacitive sensor array (CSA) implemented on an FPGA. The system captures the evaporation process of a deionized water droplet placed on the sensor array, using multiple sampling (MS) and pixel-wise accumulation (PWA) techniques to enhance signal quality and reduce random noise. The system efficiently processes and transmits the data, showcasing the gradual reduction in the droplet's size as it evaporates. This demonstration highlights the potential of the CSA system for high-throughput, real-time biomedical applications such as lab-on-chip devices.
