Researchers Spray-Paint Batteries Onto Almost Any Surface 92

Warmlight writes "Rice University researchers have created a type of lithium-ion battery that can be spray-painted onto most surfaces. 'Their batteries, outlined in Scientific Reports (abstract), are made up of five separate layers, each with its own recipe — together measuring just 0.5mm thick. To demonstrate the technique, the team painted batteries onto steel, glass, ceramic tile and even a beer stein.' What do you think this will do for future form-factors? Maybe a form-fitting PipBoy-style device that doesn't weigh 30lbs?"

    That's great and everything. But what kind of capacitance can they get out of these?

    As little as possible, one hopes, though I've never heard of parasitic capacitance [wikipedia.org] as a major consideration in battery design. But when they get down to spray painting them on surfaces, who knows? Certainly the designers of any non-trivial circuit that is sprayed onto a surface will have to deal with this phenomenon.

An algorithm must be seen to be believed. -- D.E. Knuth
