what is the piezoelectric ckts for power generation from rainwater

Today, electricity has become a lifeline for the human population. Their demand is increasing day by day. Modern technology needs an enormous amount of electrical energy for its various operations. Electricity production is the largest source of pollution in the world. Increasing concern about the gap between demand and supply of electricity for the masses has highlighted the exploration of alternative sources of energy and their sustainable use. On the other hand, the human population worldwide and therefore the demand for energy is increasing day by day in a linear fashion. It is therefore an aim of the present invention to provide a method of generating electrical energy from this growing human population which does not adversely affect the environment. This technology is based on a principle called the piezoelectric effect, in which certain materials have the ability to accumulate an electric charge of having the pressure and the voltage applied to them. Piezoelectricity refers to the ability of some materials to generate an electrical potential in response to the applied pressure. The energy collection that means energy is already available but will lose if it is not used. The built-in piezoelectric material can provide the magic of converting the pressure exerted by people moving in electric current.

In the proposed method  in addition to using the peltier sensor. A thermocouple consists of two conductors of different materials (usually metal alloys) that produce a voltage in the vicinity of the point where the two conductors are in contact. Commercial thermocouples are inexpensive, interchangeable, supplied with standard connectors and can measure a wide range of temperatures. In contrast to most other temperature measurement methods, thermocouples are self-powered and require no external form of excitation. The main limitation with thermocouples is precision; System errors of less than one degree Celsius (° C) may be difficult to achieve. Hermocouples for practical temperature measurement are specific alloy joints that have a predictable and repeatable relationship between temperature and voltage. Properties such as corrosion resistance can also be important when choosing a type of thermocouple. When the measuring point is far from the measuring instrument, the intermediate connection can be made by extension cables that are less expensive than the materials used to manufacture the sensor. Thermocouples are normally standardized against a reference temperature of 0 degrees Celsius; Practical instruments use electronic cold junction compensation methods to adjust the variable temperature at the instrument terminals.
