used to describe those devices that are optional in nature, as opposed to hardware that is either demanded or always required in principle. The term also tends to be applied to devices that are hooked up externally, typically through some form of computer bus like USB. Typical examples include joysticks, printers and scanners. Devices such as monitors and disk drives are not considered peripherals when they are not truly optional. Some people do not consider internal devices such as video capture

1. PELTIER CELL • A Peltier Cell is device which directly convert heat energy into electric energy. Peltier device consist several of thermocouples. The thermocouple have two thermo elements that spreads between the hot side and cold side of the device. Fig. 1.1 • The efficiency of this device is around 5-8 % (Wikipedia.org).Generally, older devices are made from bimetallic junctions.it was very bulky. But, now a days highly doped semiconductors are used which is made from bismuth telluride
