Microsecond photocapacitance transients observed using a charged microcantilever as a gated mechanical integrator
How light is converted to electricity in blends of organic donor and acceptor molecules is an unsettled question, partly because the spatial heterogeneity present in these blends makes them challenging to characterize. Although scanned-probe measurements have provided crucially important microscopic insights into charge generation and transport in these blends, achieving the subnanosecond time ...
متن کاملMechanical and Electronic Approaches to Improve the Sensitivity of Microcantilever Sensors.
Advances in the field of Micro Electro Mechanical Systems (MEMS) and their uses now offer unique opportunities in the design of ultrasensitive analytical tools. The analytical community continues to search for cost-effective, reliable, and even portable analytical techniques that can give reliable and fast response results for a variety of chemicals and biomolecules. Microcantilevers (MCLs) hav...
متن کاملNanotesla Torque Magnetometry Using a Microcantilever
We present a novel ultrasensitive magnetometry technique using a micromachined magnetic cantilever that is brought in resonance. The induced magnetic moment generates a torque on the cantilever, thereby effectively stiffening the cantilever spring constant and changing its resonance frequency. Experiments are in good correspondence with the presented analytical model for this frequency shift, p...
متن کاملDual-Fiberoptic Microcantilever Proximity Sensor
Microcantilevers are key components of many Micro-Electro-Mechanical Systems (MEMS) and Micro-Optical-ElectroMechanical Systems (MOEMS) because slight changes to them physically or chemically lead to changes in mechanical characteristics. An inexpensive dual-fiberoptic microcantilever proximity sensor and model to predict its performance are reported here. Motion of a magnetic-material-coated c...
متن کاملBeam Steering of Patch Antenna Radiation using Mechanical Meta-Structure
Attempt is made to modify the radiation pattern of a patch antenna using a meta-structure consisting of an array of monopole antennas in the near field. The effect of the metastructure on the radiation characteristics of the patch antenna, for different angular arrangements of the metastructure plates, has been experimentally studied.
