Deformation under electrical field
The deformation caused by the applied姑娘高清 electric field can be defined 中文版动漫by the simple formula:
Where
● S i =Δx i /x i =ΔL/L and represents tGO姑娘he strain (relative deformation) of the sample艺术飘雪 in the x i direction
● 直播直播;d 31 is the piezoelectric strain constant
Example of an element with th姑娘艺术e following characteristics:
Length: l=1cm
Width: w=2mm
Thickness: t=9µm
Applied voltage: V=200V -> E (elect美丽影院ric field) = V/t
(d 31 , d 32 , d 33 ) = (11, 10,动漫丁香花 -30) pC/N
The piezo strain constant d is given by:
Sensors: Orders of Magnitude, Voltage 姐姐直播generation
The electrical field output (E) caused by aMV视频n applied force can be defined by:
Where:
● σ i is the applied mechanical stres姑娘免费s (N/m²)
● 艺术高清;g ij is the piezoelectric voltage c姐姐姐姐onstant (Vm/N)
Example of an element with the following charac直播影院teristics:
Length: l=2cm
Width: w=2cm
Thickness: t=100µm
Compression 0.1 Bar (104 Pa) 4N 动漫影院-> σ=10000N/m²
