This poster presents the design and analysis of a novel horseshoe shaped MEMS actuator for adaptive optics. The actuation mechanism is Lorentz force enabling low current (below 10 mA) operation. The actuator combined with an overlying aluminum coated SU-8 soft polymer membrane for the mirror, together form the complete adaptive optics system to enable correction of wavefront distortion of ...

Cantilever beam-type transducers have been in great demand and explored widely in the recent years, typically in thin film form because of their sensor and actuator applications. The piezoelectric cantilever is the most preferred structure employed in technological applications. Depending on the required flexural motion and sensitivities, these piezoelectric cantilevers can be used in unimorph, ...

We present a numerical model for simulating highly nonlinear electrokinetic phenomena, which occurs at high zeta potentials. In this model, the electric double layer is realized by solving a partial differential equation (PDE) on the double-layer-inducing surface. We also allow for a nonlinear surface capacitance, which relates the surface charge density to the zeta potential of the surface. ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 µm. Such optical sensors include a detector, typically a micro-bolometer, an IR source ...

This paper presents the approach taken through the utilization of COMSOL Multiphysics 3.5a, to develop a model that simulates the flow of a magnetorheological (MR) fluid through a micro-channel. The model was developed as an aid in the analysis of a micropump that produces flow by means of displacement of a MR fluid slug within a microchannel.

Nearly seven lakh Indians die of cancer, while over 10 lakh are newly diagnosed with some form of the disease every year. Surgical resection is not always feasible in patients with hepatocellular carcinoma. Microwave Coagulation Therapy (MCT) has been used as an alternative to resection and its efficiency has been evaluated in tissue microwave irradiation from a dipole antenna causes water ...
