Abstract
We have designed and developed a configurable system that can generate and deliver a variety of electrical pulses suitable for gastrointestinal studies. The system is composed of a front-end unit, and a back-end unit that is connected to a computer. The front-end unit contains a stimulating module with 32 channels configured to generate two different current pulses, simultaneously. Commercial off-the-shelf components were used to develop front- and back-end units. A graphical user interface was designed in LabVIEW that allows configuration of the stimulation pulses through the back-end unit in real-time. The system was successfully validated on bench top. The bench-top studies showed the capability of the system to deliver bipolar, monopolar and unbalanced electrical pulses to a maximum load of 1.5 kΩ, at amplitudes up to ±10 mA with resolution of 10 μA, and pulse widths varying between 80 μs to 60 s with the resolution of 80 μs. This study reports the first multi-channel bipolar stimulator that is designed for gastrointestinal studies, and can be configured wirelessly. The system can be used for treating functional gastrointestinal disorders in future.
