Abstract
A microfluidic chip on a transparent substrate includes microchannels, and an electric layer having a heater and a sensor layout on the microchannel nearby and aside for supplying heat source and sensing the temperature individually. The sensor is close to the microchannel for controlling the temperature accurately. Hence, the microfluidic chip can measure the temperature precisely without using an isolation layer and lower energy consumptions and reduce production costs.
Claims20
A microfluidic chip, comprising:
- a main body, which is made of a transparent material and is provided with a microchannel for containing a fluid flowing therein;
- and
- an electrode layer, provided with a heater wire and a sensor wire, said heater wire is disposed in the vicinity of said microchannel of said main body, said sensor wire is disposed on one side of said microchannel of said main body, said heater wire is used to heat said fluid in said microchannel, and the temperature of said fluid is sensed by said sensor wire.
