  1. BioSemi founded in Amsterdam as a UvA Medical Physics spinout

    Founded by Robert Honsbeek, Ton Kuiper (electronic engineers), and Coen Metting van Rijn (physicist), building on Foundation Vision Research Amsterdam prototypes distributed to 40+ scientific and clinical users.

  2. ActiveTwo system released

    24-bit per-channel ADC, optical-fiber isolation, active electrodes — sets the high-end research-EEG standard.

Reputation

Iconic in cognitive neuroscience and ERP research. The 24-bit per-channel front-end and fiber-optic isolation set the high-end standard for clean, electrically isolated EEG. ActiView acquisition software is open-source LabVIEW.
