Microfluidic chip, temperature measurement method using the same, and analysis device using the same

An analytical device, comprising:

• an external current source, an external voltmeter and a microfluidic chip, wherein the microfluidic chip comprises:
• a substrate and at least one microfluidic module located on the substrate, and the microfluidic module comprises a droplet control unit and at least one temperature detection unit, and
• wherein the at least one temperature detection unit comprises a temperature sensor, a first lead group and a second lead group, the temperature sensor is fixed on the substrate, the first lead group and the second lead group are electrically connected with the temperature sensor respectively, the first lead group is electrically connected to the external current source to transmit a constant current to the temperature sensor, and the second lead group is directly electrically connect the temperature sensor and the external voltmeter such that the constant current does not flow through the second lead group.
