The fabrication of the temperature control section of PCR-chip is very important.With the help of thin-film technology and MEMS technology

the thermoelectric materials can be integrated under the chamber according to Peltier model

in order to control the temperature of chamber.Furthermore

we can switch easily between heating and cooling by changing the direction of the current.The integrated micro-fabricated PCR-chip composes of chamber

temperature sensor and thermoelectric temperature control section.
