What are transducers?

Someone suggested that the heat and vibrations in my apartment might just be caused by transducers. So I did some research and here is what I found. Long term exposure can cause a lot of health problems and it’s not meant to be a fun device. Gang Stalkers are out to hurt people and if they can’t do it one way they will do it another way.


What are they?


A transducer is a device which transfers one form of energy to another. Modern vibration measurements employ transducers which convert mechanical energy into electrical energy. A most suitable transducer for human vibration measurements is the accelerometer. This produces an electrical output (ie charge, voltage, current or change of resistance), that is proportional to the acceleration (as well as displacement and velocity : see the first lecture in this course) to which it is exposed. The most common types of accelerometers are piezoelectric or piezoresistive.
What are they used for.

a) Vibration Testing

Vibration testing, in brief, is the shaking or shocking of a component or assembly to see how it will stand up to real world conditions. It is used in applications ranging from circuit boards and aircraft to vehicles and household appliances. Conducting these tests in the field or the laboratory involves the use of data analyzers, climatic chambers, controllers, instruments and vibration exciters. Brüel & Kjær has a complete product portfolio to provide you with the whole excitation and measurement chain to establish proof of quality according to national and international standards, such as DIN, ISO, BS, MIL, IEC and ASTM.
b) Tracking

The next set of applications would involve piezoelectric cable. Piezoelectric cable behaves much the same way as flat piezoelectric transducers only the cable is much cheaper. The cable resembles the standard coaxial cable that plugs into the TV, but the piezo cable has a layer of piezoelectric polymer wrapped into it. This cable could be used to create a grid across the floor that could generate power from people walking across it, or the more viable purpose would be for tracking. These cables come with varying degrees of sensitivity. The cable could be used to track both the location and the orientation of a person in the house. Based on the way they walk, the floor might also be able to identify who the person is.

You can select an accelerometer based on requirements for Number of Orthogonal Measuring Axes, Sensitivity, Dynamic Range, Frequency Range, Electrical Output, Temperature Range and Weight. Or select from different application-oriented groups where further specifications are given: General Purpose; Structural and Modal Analysis; High Temperature; High Sensitivity; High Frequency; Miniature and Shock or Human Vibration. Cables, mounting phase response and environment specifications are other issues to be considered when selecting an accelerometer.
Human health effects.

Severe, prolonged exposure to vibration can cause injury to the body. The parts of the body most likely to be injured during exposure to whole-body vibration depend on the magnitude of vibration, distribution of the motion within the body, and the vibration frequency, direction and duration.

As mentioned before there is a shortage of conclusive evidence to establish the probability and extent of that injury or to provide a definite dose-effect relationship between whole-body vibration and injury or health damage. From the epidemiological studies, subjective data, biodynamic models and a knowledge of the physical properties of the body it is possible to establish some of the health effects:

Spinal column disease and complaints: These are perhaps the most common diseases associated with the long-term exposure to whole-body vibration, where the back is especially sensitive to the 4-12  Hz vibration range.

Digestive system diseases: Often observed in persons exposed to whole-body vibration over a long period of time. Associated with the resonance movement of the stomach at frequencies between 4 and 5  Hz.

Cardiovascular system effects: Prolonged exposure to whole-body vibration at frequencies below 20  Hz results in hyperventilation, increased heart rate, oxygen intake, pulmonary ventilation and respiratory rate.


Vibration at frequencies of about 1 Hz and below, which occur in many forms of transport, might induce motion sickness (kinetosis). It results in nausea, dizziness, vomiting and can affect the safe handling of vehicles or the performance of other tasks.

The symptoms are worst between approximately 0.125 and 0.25 Hz, and only rarely occur due to frequencies above 0.5 Hz.

Motion sickness in ships is believed to be caused by vertical oscillation. Some form of air sickness are also due to vertical oscillation of the body, but car sickness is believed to be caused mainly by horizontal motion and is associated with acceleration, braking and cornering manoeuvres.
