Circular high-Q resonating isotropic strain sensors with large shift of resonance frequency under stress
(2009)We present circular architecture bioimplant strain sensors that facilitate a strong resonance frequency shift with mechanical deformation. The clinical application area of these sensors is for in vivo assessment of bone ... -
Electrostatic force spectroscopy of near surface localized states
(Institute of Physics Publishing Ltd., 2005)Electrostatic force microscopy at cryogenic temperatures is used to probe the electrostatic interaction of a conductive atomic force microscopy tip and electronic charges trapped in localized states in an insulating layer ... -
Metamaterial based telemetric strain sensing in different materials
(Optical Society of American (OSA), 2010)We present telemetric sensing of surface strains on different industrial materials using split-ring-resonator based metamaterials. For wireless strain sensing, we utilize metamaterial array architectures for high sensitivity ... -
RF-MEMS load sensors with enhanced Q-factor and sensitivity in a suspended architecture
(Elsevier, 2010-11-09)In this paper, we present and demonstrate RF-MEMS load sensors designed and fabricated in a suspended architecture that increases their quality-factor (Q-factor), accompanied with an increased resonance frequency shift ... -
Simultaneous measurement of multiple independent atomic-scale interactions using scanning probe microscopy: data interpretation and the effect of cross-talk
(American Chemical Society, 2015)In high-resolution scanning probe microscopy, it is becoming increasingly common to simultaneously record multiple channels representing different tip-sample interactions to collect complementary information about the ... -
Time-delay estimation in dispersed spectrum cognitive radio systems
(SpringerOpen, 2010)Time-delay estimation is studied for cognitive radio systems, which facilitate opportunistic use of spectral resources. A two-step approach is proposed to obtain accurate time-delay estimates of signals that occupy multiple ...
