A Portable Thermal Cycler Using a PN Sandwich-Structure Peltier Device
We have studied a novel Peltier device having a metallic tip which is directly sandwiched between P-type and N-type thermoelectric materials. The tip can be heated and cooled directly driven by Peltier effect, resulting in high thermal response. In this study, we report the fabrication of a portable thermal cycler using a PN sandwich-structure Peltier device. The device has copper plates with minute fin to efficiently radiate heat.
