With the development of science and technology, the request of the performance of accelerometers is increasingly higher and the precision of reference directly affects the performance of accelerometers.
The ratio R1/R4 is temperature-dependent due to different types of materials.
An even better material is high ploysilicon (lightly-doped polysilicon), since it has a negative TC.
Thus, the resistors of R2, R4 are implemented by high ploysilicon material.

The chip material is usually regarded as a moving body which has uniform velocity distribution without considering the influence of material microstructure.
Therefore the velocity field of chip material is probably not uniform.
