Spray-On Computers

Jack William Bell writes "Edinburgh University has funding for a program to create spray on computers. The basic idea is to make thousands of tiny 'silicon specks' or 'smart sand' (a step larger than smart dust) which work together via wireless networking to provide 'ubiquitous computing.' No, the idea itself isn't new. But it is interesting to see someone actually working on it. The initial application is a spray you apply to the chest of heart patients, creating a sensor array to report their health back to the hospital."

One question.

How much for a dimebag?

Does anyone else not get it?

I don't know about you, but I don't really see the point of using an aerosol can to make computers. Yeah, I get the medical thing (and I think it's a good idea) but why do you have to spray it on? Why not simply apply it with some tweezers and glue? Is it funner to shake up a can, say "Close your eyes!" and press down on the little button?

With this you could take a pen and spray it and it becomes an interface in its own right.

Umm... okay... So everyone has a can of "Kwik-n-Ez Spray-on computers" sitting on their desk and then they say, "I want to interface with my computer!" shake up the can and spray their pen. "There! I typed a command, now I'd better throw the pen out and when I need to interface again I'll shake it up and spray!"

1.3 million pound grant eh?

do you really want your heart status to be "broadcast out"?

I bet shop owners would pay a lot for ability to read this. They could monitor your heart rate as you walk around the shop and notice which products make jump it up.

Combine this with RFIDs and you've got very advanced system to monitor customer,s habits.

Well... this is true... but keep in mind that it takes YEARS / decades of inhalation in order to cause a health hazard. Sandblasting and mining are two professions where silicosis is a serious concern.

I'd be less concerned for the patient, but rather for the medial personal who have to work with this stuff. Day at the beach level exposure is probally acceptable risk. Everyday exposure I'd agree with you 100%.
