This seminar will discuss the importance of tactile sensors in robotic applications, focusing on capacitive tactile sensing due to its high sensitivity, low power consumption, fast response, and low cost. It will review existing tactile sensing technologies and introduce a capacitive tactile sensor capable of measuring 3D forces, along with a custom hybrid chip designed for efficient multi-channel capacitance measurement. Applications of these sensors in robotics will be presented through demonstrations, along with a discussion of potential future applications, including low-cost electrical capacitance tomography (ECT).

The seminar will also introduce ECT as an industrial imaging technique, highlighting its advantages such as being non-invasive, radiation-free, fast, and cost-effective. An AC-based ECT system will be demonstrated, with examples of industrial applications, particularly in gas, oil, and water multiphase flow measurement. Future developments involving machine learning and AI in ECT will also be discussed.
