[Abstract]:The heating method of microfluidic in the specific region of array chip is proposed, and the 4 脳 4 array polydimethyl siloxane chip and its heating module in specific region are developed. 16 InterDigital Transducers are lithography on 128擄 YX-LiNbO3 substrate. The excited SAW drives the oil phase fluid on the piezoelectric substrate so that it can be transported to the heat transfer column in the zone to be heated, and the electrical signal is added to the InterDigital Transducer on both sides of the oil phase fluid. SAW is excited to heat the oil phase fluid, and the microfluidic in the heating zone of the array chip is heated by the heat transfer column. Taking paraffin oil microfluid as the experimental object, the microfluid heating experiment in the specific area of the array chip is carried out. the results show that SAW can effectively heat the paraffin oil microfluid in the specific area of the array chip, and under the action of 30.0dBm electrical signal power, The temperature of 7.5 渭 L paraffin oil increased from 22.3 鈩，
