Hi Roger, Thanks for your kind response. I am looking for some feature size of 50um x 50um. Other parameters have been decided yet. I am actually interested in the piezoresistive properties of CNTs, but have not start the research yet. By googling this, I can find some publications on this type of CNT printing. Just out of interest, are there any companies that have commercialized this technique yet?
