The printed/electrochemical engineering laboratory (P/EEL) at CCNY uses 3D printers to create active electrochemical electrodes for batteries and sensor applications. Their methods allow them to print these materials directly into device packaging, improving device flexibility and minimizing overall package size. Demos: electrode printing system & electrochemical/mechanical battery tester.

- City College of New York

I'm an assistant Professor at the City College of New York in the Department of Chemical Engineering and a founding member of Energy Institute of the City University New York. In one hand I hold a bunch of problems, in the other a bunch of tricks, and I generally try to, in a very Edisonian manner, shove one into the other and see what works. This can be a very efficient way of getting to a novel solution, provided one is honest about the outcome. To date the tricks have been printing novel materials, low creating small semi-autonomous computers, and a humble appreciation of electrochemistry and the problems have explored energy sources for very large and very small devices understanding losses in very inefficient, distributed processes and putting tiny, cheap computers in (at the time) odd places. Sometimes it works out. Sometimes it doesn't and I either have to find new problems and/or new tricks, and this is exactly half the fun. I am therefore very lucky to be an assistant professor in this fine department at this storied institution.
