During
the last semester,I purchased all the hardware parts that I need to construct
for the circuit. But I have a problem with the purchase because there are some
components cannot be found in the store. The component such as piezo film is
hard to find at Malaysia.So I must order the component online at the
sparkfun.com.
Below
is specification about piezo film:
Piezoelectric Film is an enabling transducer technology with
unique capabilities. Piezo Film produces voltage in proportion to compressive
or tensile mechanical stress or strain, making it an ideal dynamic strain gage.
It makes a highly reliable, low-cost vibration sensor, accelerometer or dynamic
switch element. Piezo Film is also ideally suited for high fidelity transducers
operating throughout the high audio (>1kHz) and ultrasonic (up to 100MHz)
ranges.
Piezo Film elements are offered in
four variations:
·
Silver ink screen printed electrodes
·
Lamination for higher voltage output
when bending
·
Flexible leads
·
Shielded sensors
