Buildings are responsible for around 40% of the antopogenic greenhouse gas emissions in the western world. And while the technology to mitigate these GHG emissions is available, economic as well as convenience considerations resulted so far in very few implementations. This is where our research is focused: provide the technological innovations in a manner that are both beneficial for the environment but also increase the well-being of the occupants.
The above research directions are all implemented and tested in real life conditions (in “Living Labs"):
The HiLo lightweight living unit is being constructed as part of the NEST project at EMPA. Two research groups of the Institute of Technology in Architecture, ETH Zurich, are responsible for the project; the Assistant Professorship of Building Structure (BLOCK Research Group / BRG) and the Assistant Professorship of Architecture and Sustainable Building Technologies (SuAT). The two teams develop their ideas with foreign partners, with Supermanoeuvre from Sydney and Zwarts & Jansma Architects (ZJA) from Amsterdam. The two-story penthouse is designed as energy-plus building and should be completed according to plan in the summer of 2015. The adaptive facade and the occupant centered control are only two of the total five innovations that are being displayed in this living lab.
The ETH House of Natural Resouces (HoNR) is an office building for the Laboratory of Hydraulics, Hydrology and Glaciology from ETH Zürich and will serve as a showcase building of a sustainable and reliable timber construction for students and researchers, among others. The building has multiple innovative aspects, such as the use of beech for structural elements, the implementation of a permanent sensor network, and the performance of in situ tests at different construction stages. We will implement the adaptive solar facade as well as the occupant centered control approach here.
Retrofit measures are an effective means to improve both the heating energy and carbon footprint of a building. On one hand, reducing the losses through the envelope reduces the energy consumption. On the other hand, updating the heating from a fossil-fuel based system to an emission-free one bears the potential for CO2-emission free operation. This project explores how simple measurements can provide useful insight into the energetic behavior of a building and allow to derive models to predict the effect of the retrofit measures.Z.

[...] it would be interesting in surgery if you could swallow the surgeon. You put the mechanical surgeon inside the blood vessel and it goes into the heart and looks around.
[...] How do we make such a tiny mechanism? I leave that to you.

We are developing a modular robotic system that can be swallowed and will assemble inside the G.I. Tract for therapeutic and diagnostic procedures. ETH Zürich is one of four European universities participating in this project, led by Paolo Dario at Scuola Superiore Sant'Anna.
My research involves the investigation of the self-assembly of the ARES robot inside the stomach. Using a specific magnet configuration on the connection face, assembly success rates of up to 90% are possible.
This project aims at developing magnetic microrobotics for ophtalmic surgery.
I am involved in developing the magnetic model for assembled-MEMS microrobots. The model is validated through FEM simulations and experiments, and captures the characteristics of complex 3-D structures. It allows us, for the first time, to consider full 6-DOF control of untethered devices.
The Swiss French Television (TSR, Nouvo, Dec.5, 2008) reported on both projects:
A German (SF1, Einstein, Feb.5, 2009) version is also available.
In this project, we consider world's first really untethered microrobots that are driven by oscillating magnetic fields. The oscillations are converted into mechanical energy and rectified using a spring-mass impact system with friction, leading to stick-slip motion.
I model this system using non-smooth multi-body dynamics and can explain several unintuitive behaviors that are experimentally not explicable because of the nature of the devices. The microrobots are fabricated and characterized experimentally by Dominic Frutiger.
