Mathematical modelling and analysis of temperature effects in MEMS based bi-metallic cantilever for molecular biosensing applications

Abstract EN

As Lab-on-Chip platforms with micro-and nano-dimensions evolve biosensors using miniaturized and high-sensitivity cantilevers are becoming more attractive.

Although these sensors function in non-isothermal situations, computational mathematics generally ignores the temperature.

Conversely, biosensors can’t be designed with a single-layered cantilever.

Yet, in Nano-Electro-Mechanical-Systems, the influence of temperature is more likely to be dominant since the surface-to-volume ratio is higher.

In the context of this conclusion, the mathematical modelling comprises temperature and the associated material attributes.

This work presents a simple and direct analytical technique for analysing the control of bimetallic cantilevers with NEMS-based sensing and actuation mechanisms.

Methodological techniques were used to develop and solve some well-known models of mathematical equations.

Parametric analysis data is a major factor in the functioning of all of the other works studied.

The findings of FEA comparisons and experiments reveal that the mathematical model's predictions are more than 20% correct.
