The International Exhibition of Inventions of Geneva 2022
7 Apr, 2022

Congratulations to Professor CHEN Shih-Chi, Professor LAU Tat Ming Darwin and Professor Yeung YAM for winning one Gold Medal and two Silver Medals at the International Exhibition of Inventions of Geneva 2022!

Gold Medal: Ultrafast Oscillating Blade Microtome

Principal Investigator: Professor CHEN Shih-Chi

Project Description:

The new oscillating blade microtome enables the precise sectioning of various ultrasoft tissues, fresh tissues and fixed whole organs that are hard to process before. Sectioning of soft tissues is achieved by exploiting the viscoelastic effect, i.e., the tissue self-stiffens at high frequency. By exploiting the concept of active vibration control, the controller actively generates the dynamic force and torque for cancellation based on the sensing of microtome motion and unbalanced force. The ultrafast oscillating blade microtome has the highest oscillation frequency to 350 Hz, which ensures the best cutting performance.

Silver Medal: Cable-driven Inspection Robot for High-rise Building Façade

Principal Investigator: Professor LAU Tat Ming Darwin

Project Description:

This is a mobile cable robot system with four components to perform contact-based façade inspections. It simplifies the current workflow, eliminating the need for working at height and providing a quantitative, digital diagnosis.

Silver Medal: CU-Brick Robotic Brick Construction Robot

Principal Investigators: Professor LAU Tat Ming Darwin, Professor Yeung YAM and Professor Adam FINGRUT (School of Architecture)

Project Description:

The CU-Brick is an automated robotic system with four primary components that constructs brick structures: a cable-driven parallel robot, an automated brick delivery system, a human-robot collaborated mortar application and a computational design framework. CU-Brick allows large-scale brick structures of complex geometry to be constructed due to its high levels of accuracy, efficiency and automation.
