Electrical and mechanical functions integrated in the nanoscale range led to the development of the new age devices, Nanoelectromechanical systems (NEMS). These devices because of their size, they come with properties such as reduced mass, high quality factor (Q factor) and very high fundamental resonance frequencies. These qualities of NEMS makes them desirable for numerable applications such as components of signal processing devices, actuators and high speed sensors.
NEMS can be used to construct resonators through a process of surface nanomachining to achieve frequencies of above 10Ghz. The operation at such high frequency range opens gateways to many new potentials such as fast scanning probes, resonators and active oscillators. Active …show more content…
Due to this, they can be a key component in building many types of sensors as they are highly sensitive to external dampening forces. High Q value allows deflection and resonant sensors to be sensitive to the applied force and cut down arbitrary mechanical fluctuation in the system. Also their low consumption power and the ability to respond to only a narrow range of frequencies (high Q factor) make them desirable for filtering signals at the RF front end of a radio receiver and various signal processing applications. One of the new advancements is the use of Graphene for the fabrication of NEMS. With its breaking strength of 42 N/m, Young’s modulus of 1 terapascals and light weight, it achieves high resonance frequency which makes it popular in the field of RF signal …show more content…
The displacement caused due to bending can be measured with the change in capacitance, piezoresistivity, piezoelectricity and optical beam deflections. Hence the state of the cell, whether malignant or benign, can be determined by identifying the protein in the cell. Uric acid and dopamine can be detected by electrodes composed of Zinc Oxide nanowire on 3D graphene foam. Abnormal quantities of uric acid is a symptom of many diseases such as Parkinson’s disease and gout. Dopamine levels when low, can lead to schizophrenia and Parkinson’s disease as well. Detection of E. coli bacteria can be performed by using different sizes of Silicon Nitride cantilever beams. Silicon Nitride beams can also be used for the detection of double stranded
