Nanomagnet Logic – From Concept to Prototype

Bernstein G.H., Butler K., Li P., Shah F., Siddiq M., Csaba G., Hu X.S., Niemier M., Porod W., University of Notre Dame, US

As the semiconductor industry foresees an inevitable slowing of Moore's Law, many researchers are trying to develop new technologies that go beyond CMOS, in speed, density, cost, or some other desirable metric. Notre Dame has [...]

The use of interdigitated microelectrode structures for the detection of exposure to simulated airborne environmental dust

Townsend R.L., Rocks S.A., Dorey R.A., Tearle S., University of Surrey, UK

Particulate matter is ubiquitous in the environment however industrial processes increase the amount released in the air. Here we show the initial development of a novel sensor capable of detecting airborne particulate matter in real [...]

Local Synthesis of CuO Nanowires on CMOS Microhotplates for Gas Sensing Applications

Steinhauer S., Maier T., Mutinati G.C., Rohracher K., Siegert J., Schrank F., Koeck A., Materials Center Leoben Forschung GmbH, AT

CuO nanowires are locally synthesized on CMOS microhotplates leading to the realization of functional gas sensing devices. Only approximately 20mW are needed in order to heat the CMOS microhotplates to a temperature around 350°C, which [...]

Flexible Microsensor for Shape Detection

Beharic J., Lucas T.M., Senousy Y.M., Harnett C.K., University of Louisville, US

Modern techniques used in microelectromechanical systems (MEMS) sensor fabrication are adequate for use in most of today’s planar devices, which do not require flexibility to function. However, it’s difficult for a rigid structure to conform [...]

Strain gradients in poly-SiGe nanocantilevers: experimental and finite element modeling studies

Asafa T.B., Ladoke Akintola University of Technology, NG

One of the fundamental structural requirements for successful performance of N/MEM devices such as nanoswitches, nanoresonators and biosensors is low strain gradient. Excessive strain gradient leads to unwanted deflection, which consequently alters the dynamic and [...]

Optimization of a Poly-SiGe MEMS Xylophone Bar Magnetometer based on its equivalent circuit

Rochus V., Farghaly M., Rottenberg X., Tilmans H.A.C., IMEC, BE

This paper presents the optimization of a poly-SiGe-based MEMS Xylophone Bar Magnetometer (XBM) using a novel characterization method based on the measurement of the forward/backward transmission gains S21/S12 of the XBM treated as a two-port [...]

CMOS-Compatible Thermally Actuated MEMS Viscosity Sensor with Aluminum on Silicon Membrane

Puchades I., Fuller L.F., Lyshevski S.E., Rochester Institute of Technology, US

This paper presents viscosity measurements performed on standard commercially-calibrated oils as well as to motor oils measured on a commercial cone-and-plate viscometer. Figure 2 shows the response of the sensor, in the frequency domain, when [...]

Charge Pumping for High-force, Large-displacement MEMS

Harvey IR., Baker B., Hogan A., Ford K., University of Utah Nanofab, US

Instead of making machines smaller that work well in the macro world, we envision a new class of machines that are specifically designed to take advantage of what works well in the micro-scale world. These [...]

Nanotechnology-Enabled Microthrusters:Nanoenergetic Materials and MEMS Paradigm

Puchades I., Hobosyan M., Fuller L.F., Liu F., Thakur S., Martirosyan K.S., Lyshevski S.E., Rochester Institute of Technology, US

Microthrusters are used in flight and underwater platforms. The MEMS-technology microthrusters with nanostructured energetic composites increase thrust-to-weight ratio and ensure the overall requirements. The integrated MEMS micromachining ensures fabrication simplicity, affordability, robustness, integrability, compatibility and [...]

Design and Characterization of a MEMS Thermal Actuator and a Locking Switch for Telecommunication Applications

Dellaert D., Doutreloigne J., Ghent University, BE

This paper describes the design and characterization of a novel thermal actuator used in a locking switch. Because of the locking mechanism, no energy is needed to stay in the open or closed state. The [...]
