The designed implantable electrical stimulator is used for treatment of functional gastrointestinal disorders. This stimulator uses μC / OS-Ⅱ real-time kernel to build a stable and high effective software system. The hardware system based on STM32F103 completes tasks including generating stimulus pulses and sampling pressure signals in gastrointestinal tracts. The stimulator communicates with outside controller by wireless communication module
receives control command and sends pressure datas to outsider memorizer for storage. Experimental result shows that the prototype output waveform is normal and sampled pressure information can be transmitted precisely.The scale of parameters set by electrical that stimulator is broad enough for vivo experiments.
