The Nanochap High-Precision TENS Device NPT210601 is designed specifically for basic research in the life sciences. Incorporating an in-house-developed neural stimulation chip, it provides programmable current output over a wide range with high accuracy and supports multiple waveform types. A selection of electrode types allows the system to accommodate a variety of experimental paradigms, including transcutaneous stimulation, muscle stimulation, cerebral cortical stimulation, stimulation of deep brain nuclei, and experiments using animal models. It provides stable, reliable hardware support for research into the modulation of neural signals.
