HydroDot

HydroDot was a U.S. neurodiagnostic medical device company that developed disposable EEG electrode application systems designed to simplify and speed electroencephalography setup. Its products included the StatNet/Model 3100 system, HydroDot biosensors, and associated headpiece-based EEG application components intended to improve comfort, repeatability, and compatibility with standard EEG equipment. The company focused on brain monitoring workflows rather than therapeutics, serving clinical EEG use cases such as neurology, epilepsy, and related diagnostic settings. HydroDot appears to have been a small private company founded in 2007 in Massachusetts, and its branded products are now marketed through Bio-Signal Group's broader neurodiagnostic platform.
