Self-Propelled Microrobots​

The self-propelled microjets we model are fabricated at the Leibniz Institute for Solid State and Materials Research in Dresden (Video on this page: Khalil et al. TRO 2014)

General Information: Self-propulsion is essential to achieve locomotion at micro and nano scales. Once self-propulsion is acheieved,  it is possible to direct and/or drive these robots via the action of a magnetic field without the need of onboard power supply and control system. We focus on achieveing self-propulsion by the catalytic decomposition of hydrogen perovide solution into water and oxegen. The ejection of oxegen bubbles provides a propulsive force that enables the microrobot to move and achieve non-trivial applications. 

Development of a Self-Propelled Microrobot using Calcium
Carbonate and Vinegar Fuel

Remember what happens when we put an egg in a bowl and pour vinegar until the egg is covered. Bubbles will appear after a few moments. Egg shells contain calcium carbonate (CaCO3). It reacts with the vinegar’s active ingredient, i.e., acetic acid (CH3COOH). This reaction generates a salt called calcium ethanoate, some water, and bubbly carbon dioxide gas. Now let us break the shell of the egg into small fragments and observe the behaviour of these fragments under a microscope. We expect that the ejecting carbon dioxide bubbles would provide a propulsive force that would enable the fragment to move.

​Structural Optimization of Self-Propelled Microrobots

​Over the past decade, external actuation of man-made robots at the nano- and micro-scales have shown potential to revolutionize medicine and technology. It is possible to direct and/or drive these robots via the action of a magnetic field without the need of onboard power supply and control system. In this project, we will focus on the structural optimization of the microjets to maximuze their speed in low-Reynolds number regime.
