摘要
We have developed a bulk micromachined calorimeter with a sensitivity of 1.5 nW/Hz(1/2) and a 1 ms time constant using a thin film thermopile as the sensing element. The thermopile consists of seven titanium and bismuth thermocouples with a total Seebeck coefficient of 574 muV/K. The device is capable of measuring enthalpies in chemical or biological reactions in volumes as small as a few picoliters. The device can be fabricated and operated in a massively parallel fashion in combination with ink-jet printing technologies in air and at room temperature, making it ideally suited for biological and biochemical experiments.
