Welcome to the Acoustic Robotics Systems Lab

The acoustic robotics systems lab (ARSL), located in the Binnig and Rohrer Nanotechnology Center, headed by Prof. Daniel Ahmed, is engaged in developing innovative, cutting-edge research in micro and nanorobotics and systems for life science applications, diagnostics, and translational medicine. The lab focuses on

novel micro- and nanosystems for life sciences and biology
micro- and nanorobots for in vivo navigation
investigation of disease models in microfluidics and small animal models
translation of the new technologies into healthcare applications
ultrasound-assisted additive manufacturing

Researchers at ETH Zurich have developed a tiny robot that mimics the movement of a starfish larva. It is driven by sound waves and equipped with tiny hairs that direct the fluid around it, just like its natural model. In the future, such microswimmers could deliver drugs to diseased cells with pinpoint accuracy.

Additional Information

The mission of ARSL is to develop innovative acoustic-based technologies for applications in biomedical engineering, diagnostics, and translational medicine in developed and developing nations.

Why Acoustics?

High frequency acoustic fields at moderate levels of pressure is regarded as a safe, non-invasive, and relatively inexpensive procedure, and it is used extensively in clinical diagnostics and therapeutics.
