Abstract

The invention provides a wireless pneumatic / hydraulic microfluidic module, belongs to the field of microfluidic, and aims to solve the problems of large size, high packing difficulty and cost, and low networking and intelligentization possibilities of the conventional gas drive module of a pneumatic microfluidic chip. The wireless pneumatic / hydraulic microfluidic module is characterized in that pressure medium gases enter double T-shaped micro-channels which are connected in series from medium entering connectors, and are adjusted by two micro-valve drive components, so as to realize high-precision pressure medium output of the wireless pneumatic / hydraulic microfluidic module. A pressure control closed-loop principle adopted by the wireless pneumatic / hydraulic microfluidic module is as follows: a pressure sensor detects a pressure signal of an output medium; the pressure signal is denoised via a filter circuit module; after arithmetic processing of a controller, control signals are output to the micro-valve drive components, so as to realize pressure adjustment of the output medium finally. A GSM module is adopted for communication between the controller and mobile equipment, a wireless module is adopted for communication between the controller and a host computer, and both the GSM module and the wireless module can be used for remote setting or monitoring of the pressure value of the wireless pneumatic / hydraulic microfluidic module, and displaying a 'pressure-time' variation curve in real time.
