Abstract-The main aim of this review paper is to represent a general study performanceof stress, which describes the phenomenon of stress Measurement and its types.The basic types of stress sensor and their technical advancements, limitationsand significant is also discussed in this paper. Now a days the PiezoelectricSensor are very convenient to detect the stress distributions over surface ofthe material as well as the Piezoelectric Sensor is used to detect thevibration also. In this study an attempt has been taken to discuss the variousform of stress sensors are used in the different application. Keywords- Stressmeasurement, Stress sensor, piezoelectric sensors,  Introduction        We all are aware about the stresscalculations by different formulas but in this paper we are going to studyabout some sensors which convert mechanical stress into electric signal .

There aredifferent types of sensors are available in market. That sensors are classifiedaccording to their work.     Stress is nothing but the force appliedper unit area. By using piezoelectric sensor we can calculate stress easily.                                      Stress =  Where, P = force            A = area  LITERATURE REVIEW                                 Usually electrical orelectronic that convert’s one type of energy to another with the help of deviceis known as transducer. In engineering most transducers are either sensors or actuators.

Transducershas sub division as Actuators. Actuators are devices which transform an input signal(mainly an electrical signal) into motion.Sensor: a physical, chemical or biological Quantity are converted into anelectronic signal is sensors.The example of it is thermistor convert temperature to? electrical resistance  Sensors classification Based on quantity to bemeasured Mechanical: Length, area, volume, all time derivatives such as linear/angular,Velocity/acceleration, mass flow, force, torque, pressure,acoustic wavelength and intensityThermal: Temperature, (specific) heat, entropy, heat flow, state of matter.

Electrical: Voltage, current, charge, resistance, inductance, capacitance,dielectric constant, Polarization, electric field, frequency, dipole moment.Magnetic: Field intensity, flux density, magnetic moment, permeability.Radiant: Intensity, phase, wavelength, polarization, reflectance, transmittance,refractive index.Chemical: Composition, concentration, reaction rate, pH,oxidation/reduction potential. sensor work as follow:-
