Scientific Effects and Phenomena | Elaborate |
---|---|
Compression | The material yields to compressive stresses, resulting in a reduction in volume. The counterpart to compressive force is tension. Simply put, compressive force is a pushing force. |
Deformation | An applied force causes a change in the shape or size of an object. Types of applied forces are tension (pull), pressure (push), shear, and bending or torsion (twist). Deformation is often referred to as strain. |
Ellipse | The trajectory or path of a point in the same plane where the sum of the distances from a moving point to two points is constant is called an ellipse. A circle is a special kind of ellipse, in which case the ellipse is called an alternative to a circle. |
Parameters | Ellipsoidal Gold Nanoparticle Aspect Ratio Size |
---|---|
Requirement 1 | Needs to be large to increase the electric field coupling region |
Requirement 2 | Needs to be small to reduce the half-peak full width and improve accuracy |
Programmatic | Vantage | Drawbacks | Estimation |
---|---|---|---|
1 | The performance parameters of the sensor can be effectively improved | Increased demand for production accuracy | Practicable |
2 | Effective bonding of the membrane material to the sensor | Increased production difficulty | Practicable |
3 | Can effectively increase the electric field strength | Increased production difficulty | Practicable |
4 | The electric field strength can be significantly increased | Experimental feasibility is low and costly | Impracticable |
5 | The electric field strength can be significantly increased | Experimental feasibility is low and costly | Impracticable |
6 | Sensitivity improvement effect is obvious | Resulting in a broadening of the full width of the half-peak of the spectrum | Practicable |
