I wondered the same, and it's actually answered on the page: Why is our funding goal just $1? Chibitronics is an academic research project. The work to develop this technology will proceed whether or not others would like to participate in our research project. Although the circuit stickers featured in this campaign have been produced in small volumes, they were produced using techniques suitable for mass production -- we are "prototyping in production". If just one person backs this project, we're still perfectly happy to build and ship a single unit, yet we have the process scalability to meet virtually any demand. It's a bit weird, but I guess they're using it basically to measure demand and size the initial order(s).
