Comparative analysis of sensing responses between the comb-type and commercial microcantilevers.
Utilizing static charge interaction to assess and compare sensor sensitivity.

Main Results:

The comb-type microcantilever exhibits a significantly larger resonant frequency change compared to the commercial cantilever under static charge interaction.
Despite similar total surface areas, the regional surface area distribution in the comb-type design is critical for enhanced sensitivity.
The study validates the improved sensitivity of the novel microcantilever design for mass sensing.

Conclusions:

The proposed comb-type microcantilever design offers superior sensitivity for mass sensor applications.
The strategic design of regional surface area is a key factor in achieving high-sensitivity microcantilever sensors.
