What is piezoelectricity?
Q: What is piezoelectricity?
A: Piezoelectricity is the ability of a material to generate a small electrical voltage when its shape is deformed.
Q: What percentage change is required for a piezoelectric material to generate electricity?
A: A piezoelectric material can generate electricity by as little as a 0.09% change in its shape.
Q: How much electricity can a piezoelectric material produce at standard power output?
A: A piezoelectric material can produce 12mAh worth of electricity at 230V (standard power output).
Q: Does the volume or surface area of a piezoelectric material change when it is deformed?
A: No, the actual values of a piezoelectric material's volume or surface area do not change when it is deformed. Only the ratios of each axis (x, y, and z) are altered.
Q: Can a piezoelectric material become sharper when processed through heating and cooling?
A: Yes, when processed through heating and cooling, piezoelectric crystals become sharper. This process makes the material much more sensitive to changes in pressure and increases its resistance to compressive stress.
Q: What would impede the ability of a piezoelectric material to function?
A: Compressive stress can impede the ability of a piezoelectric material to function.
Q: Is it important to note the actual values of a piezoelectric material's volume or surface area?
A: Yes, it is important to note that the actual values of a piezoelectric material's volume or surface area do not change when it is deformed, only the ratios of each axis.
