Gathering occupancy data is considered as one of the grand challenges in building information modeling. Direct occupancy detection methods, such as the typical passive infrared (PIR) motion detectors detect motion rather than presence and are difficult to retrofit into existing buildings. In-direct methods, e.g., measuring CO2 levels as a… read more

Non-Smooth Dynamics Modeling of Wireless Resonant Magnetic Microactuators
In this project, we considered the 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… read more
Intraocular Microrobots and Control Using Field Gradients
This project aimed at developing magnetic microrobotics for ophtalmic surgery. I was 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… read more
