Michael is a world expert in Nano-conductive inks. Michael's PhD thesis was on Conductive Nano-Silver ink. Based on his academic work, nano-silver ink was commercialized for Xjet Solar and Nano-Dimension. Michael was Co-Founder and CTO of ClearJet which used inkjet-printed Nano-Silver rings to provide excellent conductivity and transparency for ITO replacement.
Michael holds a PhD, MSc, BSc in Chemistry from the Hebrew University of Jerusalem.
Just print and sinter for two seconds using a standard $200 office laminator.
Until now, attempts to develop simple methods for the use of Copper inks have had limited success, as oxidation has undermined conductivity.
Copprint inks enable high precision and full flexibility at all scales of printed electronics applications.
This SEM image shows the copper nano particles which are about 80 nano-meter in size.
After two seconds of sintering, large clusters of copper are created achieving high conductivity. Up to 50% bulk copper conductivity is achieved depending on the specific ink and sintering temperature.
After two seconds of sintering, large clusters of copper are created, achieving high conductivity. unlike directional sintering (e.g. photonic sintering) the sintered pattern is homogenous and the morphology of upper and lower parts are the same.
