AI Technical Summary
The sensitivity and accuracy of existing electrical quantity sensors are easily limited by the quality factor in LC resonators and are susceptible to manufacturing defects and disorder, making it difficult to achieve high sensitivity and robust sensing effects.
Design a non-Hermitian topology circuit. By selecting a non-Hermitian SSH model, construct a corresponding non-Hermitian topology circuit. Utilize non-reciprocal capacitance and Kirchhoff's equations to ensure that the circuit's characteristic equations are consistent with the model. This enables the circuit to exhibit exceptional sensitivity to frequency shifts in the topology's zero energy mode and changes in the physical quantities to be identified, while also possessing robustness to boundary perturbations.
It achieves the ability to exponentially amplify changes in physical quantities caused by minimal boundary perturbations under limited noise conditions by increasing chain length, exhibiting high sensitivity and strong robustness, immunity to the effects of component disorder, and stable sensor performance.
