NTRODUCTION
Today, in many areas, the use of measuring
instruments remains one of the daily
requirements. The fulfillment of the task set
correctly and in accordance with the established
standard largely depends on the measurement
work carried out in them [1-4]. Therefore, in the
development of measuring instruments used in
various fields, in order to increase the efficiency

and accuracy of measurements, physical effects
that occur in various semiconductor, conductor,
and dielectric materials are widely used.
Piezoelectric effects in dielectric materials are
also widely used in the development of measuring
instruments. This effect is used as the main one
not only in the development of measuring
instruments, but also in many devices in which it
is necessary to convert mechanical energy into
electric field energy [5-7].
T
HE MAIN PART
The piezoelectric effect in dielectric materials is a
phenomenon where polarization occurs when
dielectric materials are subjected to mechanical
pressure. Piezoelectric effects of this type are
properly called piezoelectric effects. When an
external electric field acts on dielectric materials,
deformation occurs in such materials, this effect
is called the inverse piezoelectric effect. Dielectric
materials with a piezoelectric effect are called
piezoelectric
elements.
Typically,
such
piezoelectric elements have both direct and
reverse piezoelectric effects. Literary Analysis .
Many scientific studies have been carried out on
the use of piezoelectric elements in the
development of measuring and control devices in
various fields. In particular, the Malaysian
scientist Arshed Abdulhamed Mohammed in the
article "The role of piezoelectric elements in
determining the mechanical properties of solid
industrial materials" considered the possibility of
using piezoelectric materials in determining the
deformation of solid materials and measuring the
degree of deformation [1,6,7]. In addition, the
scientist of the Silesian University of Technology,
Marek Plakzer, in his article "The use of
piezoelectric transducers of the MFC type in
mechatronic measuring systems - the impact of
damage to the mechanical subsystem on the
operation of the system" highlighted the
possibilities of their use as measuring
instruments in mechatronics [2,5,8]. Sometimes it
will be necessary to measure vibroacoustic
signals of extremely low frequency from 0 Hz. Of
course, there are rather expensive specialized
sensors for this purpose, but cheap piezo emitters
can also be adapted. They are used to generate
sound (tweeters) in various mobile devices. The
fact is that piezoelectrics work in different
directions [9,10]. Structurally, the piezoelectric
element is a piezoceramic with applied
electrodes. Piezoelectric elements can be of
various shapes: in the form of disks, rings, tubes,
plates, spheres, etc. To receive a digital signal, you
can use the Arduino board and connect the piezo
element to its analog input (Fig. 1). But here a
problem arises - during the operation of such a
sensor, the signal gradually increases and goes
into saturation. This situation can be simulated by
using a high-resistance potentiometer and a high-
value capacitor instead of a piezoelectric sensor
(a piezoceramic with two metal plates is a
capacitor).

Fig.1. Connection diagram of the piezoelectric element
It is because of him that problems arise, because.
it is charged with charges from the piezoelectric
element and cannot be discharged, because. ADC
resistance is quite high.
For testing, the following code for Arduino is
suitable :
void setup() {pinMode ( A0, INPUT); Serial.begin
( 9600);}
void loop() {Serial.println ( analogRead
(A0));delay( 10);}
C
ONCLUSIONS
With this device, you can get objective data on
fairly strong vibrations, for example geological.
From biomedical signals, it is possible to detect
only the pulsations of the arteries in order to
calculate the heart rate. For greater sensitivity, a
DC amplifier with high input impedance and a
low-pass filter should be placed between the ADC
and the sensor.
