A new sensing method employing a computer-designed broadband voltage pulse sent to an electromechanical resonator is suggested and demonstrated. The pulse spans a user-defined bandwidth around a user-selected center frequency so as to include at leas

Silicon micro cantilevers are used as highly sensitive transducers for a wide range of physical, chemical and biochemical stimuli. Vibrating the cantilevers at higher-order resonant modes can achieve extra sensitivity, but the difficulty lies in dete

The mechanical oscillation of the heart is fundamental during insect metamorphosis, but it is unclear how morphological changes affect its mechanical dynamics. Here, the micromechanical heartbeat with the monarch chrysalis (Danaus plexippus) during m

Silicon micro cantilevers are used as transducers for a wide range of physical, chemical and biochemical stimuli, where they exhibit exquisite sensitivity (10?18?g, 10?15?J, 10?9?M, etc) over a wide range of temperatures (100?mK?1300?K). This is acco

Diseased tissues exhibit changes in mechanical properties and thus possess clinical diagnostic significance. We report the design and development of a Fine Needle Elastography (FNE) prototype device integrated with Fine Needle Aspiration Cytology (FN

We present an analytical model for single mode, multiply reflected, external cavity, optical fiber Fabry–Perot interferometers in the low finesse regime using simple geometry and the Gaussian beam approximation. The multiple reflection model predic

We present a new servo controllable force sensor that exploits photon momentum forces for the identification, calibration, and control of its dynamic properties. The sensor comprises a millimeter-scale glass cantilever, a low-noise fiber interferomet

Mechanisms for controlled approach of a probe tip toward the sample surface are essential in high resolution imaging by scanning probe microscopy (SPM). This work describes the development and performance of an inertial sliding drive capable of trans

Here we report application of imaging interferometry to the study of nanomechanical motion in biosensors and living biological systems. Using strobed interferometric microscopy we are able to probe the dynamic behavior of individual (100 x 500 x 1 mi
