Publication number: 20210260368Abstract: The present invention provides a microelectrode, comprising a flexible layer, an electrically conductive layer and a plurality of platinum dendrite structures, wherein the electrically conductive layer is arranged in the flexible layer, and wherein on the surface of the flexible layer are a plurality of grooves within which the electrically conductive layer is revealed partially, and wherein each of the groove is provided with one platinum dendrite structure therein. The plurality of grooves serve as focal electrodes distributed uniformly, with smaller electrode sites and more recording points. The modified platinum dendrite structures increase the surface area, electrical performance, biocompatibility and service life of the microelectrode. Besides, creating virtual electrodes by current steering technique increases the number of stimuli received by microelectrode during use, and improves its resolution in applications.Type: ApplicationFiled: July 9, 2019Publication date: August 26, 2021Inventors: Qi ZENG, Tianzhun WU

Publication number: 20210146350Abstract: A device for generating a droplet array, which comprises a substrate, a roller on the substrate, and a microgrooved chip on the outer surface of the roller, wherein a sealant is on a surface of the substrate close to the roller and the microgrooved chip comprises a chip body fitted to the roller and an array of microgrooves arranged on the chip body, the array of microgrooves consisting of a plurality of microgrooves arranged at intervals on the chip body. When the roller rolls, liquid between the substrate and the roller enters the microgrooves and forms droplets while the microgrooved chip detaches from the roller and combines with the sealant which seals the microgrooves, generating a droplet array. The device generates a droplet array having uniform droplet size, good repeatability. Further, the method is simple and highly efficient, and has broad application prospects in the fields of medicine and biology.Type: ApplicationFiled: December 17, 2018Publication date: May 20, 2021Inventors: Zhiting PENG, Tianzhun WU
