This isolated constant current biphasic nerve stimulator is controlled by an analogue voltage input which the DS5 translates into an isolated constant current stimulus (up to ±50mA), precisely replicating the shape of the input waveform. While It has been designed for nerve excitability research, the DS5 should be of interest to anyone wishing to control skin surface stimulation protocols via software/hardware combinations capable of producing a suitable input voltage waveform e.g semi-automated pain research or sensory threshold testing. The DS5 was developed in collaboration with Prof. Hugh Bostock (UCL, London) and can be used with his QtracW software (see below) for nerve excitability research studies. A series of Nerve Excitability Workshops are planned for 2014, please contact us for more details.
