The authors have developed a Bio-calorimeter with nano-watt level resolution with a MEMS thermopile sensor. Important factors of the development are a highly sensitive heat sensor, a stable amplifier system of minute sensor signal and stable temperature control of the isothermal bath. In this study, we improved the stability of the isothermal bath in one milli-Kelvin level by using a current control type Peltier drive circuit. Compensation heating type differential calorimeter was also introduced to improve quantitativeness in calorimetry. A prototype calorimetry was tested in thermometry in a yeast growth process and a germination process of a single seed.
