The use of hydrogels for biomedical engineering, and for the development of biologically inspired cellular systems at the microscale, is advancing at a rapid pace. Microelectromechanical system (MEMS) resonant mass sensors enable the mass measurement of a range of materials. The integration of hydrogels onto MEMS resonant mass sensors is demonstrated, and these sensors are used to characterize ...

Piezoelectric microelectromechanical systems (MEMS) resonant sensors, known for their excellent mass resolution, have been studied for many applications, including DNA hybridization, protein-ligand interactions, and immunosensor development. They have also been explored for detecting antigens, organic gas, toxic ions, and explosives. Most piezoelectric MEMS resonant sensors are acoustic sensors...

Nanomechanical resonant sensors that are based on detecting and tracking the resonance frequency deviations due to events of interest being advocated for a variety applications. All sensor schemes currently in use subject basic trade-off between accuracy speed, while there is great improving both order enable unprecedented widespread Based thorough understanding characteristics current architec...

Power supply is a bottle-neck problem of wireless micro-sensors, especially where the replacement of batteries is impossible or inconvenient. Now piezoelectric material is being used to harvest vibration energy for self-powered sensors. However, the geometry of a piezoelectric cantilever beam will greatly affect its vibration energy harvesting ability. This paper deduces a remarkably precise an...

We have demonstrated a new approach for detecting biomolecular mass in the aqueous environment. Known as the suspended microchannel resonator (SMR), target molecules flow through a suspended microchannel and are captured by receptor molecules attached to the interior channel walls [1]. As with other resonant mass sensors, the SMR detects the amount of captured target molecules via the change in...
