We strive to provide researchers with the latest breakthrough technologies to improve understanding of organs such as the brain and heart and their related illnesses.


Microelectrode arrays (MEA) meet CMOS technology

Our disruptive microelectrode array (MEA) technology revolutionized brain research by enabling a better investigation of neuronal networks. Our pioneering work on CMOS technology allowed researchers to visualize signal propagations occurring at a sub-millisecond scale between thousands of cells for the first time.
