Hi Guys, So I'm a UK student who will be applying to college in the middle of next year. Along with applying to Uni's in the UK via UCAS, i also want to broaden my choices. I like the idea of using other things apart from academics in order to gauge admissions. However, truth be told, i have...

but anyway, any ideas on how contact with the RFID reader could trigger the heating mechanism (see above)

because the target prisons (in the middle east) have guards that aren't expert snipers. The dart could easily hit something important (eg. head eye). Also, they can quickly take it out, causing the sedative to possible not be inserted properly. Also, its painful. The bracelet is much less...

The aim of the project is to be a prototype for extra prison security. I actually think the RFID thing will work. Instead of being remotely activated like previously thought, i think that i would like to make something that detects if the bracelet is too close to the source (which is stuck on...

I am curious as to how much power i needed for this. Double/triple A, or something smaller? Also, how could i get the RFID, as suggested by [berkeman] to activate it? Yes, this is meant to be disposable..

hmm.. let's say around 25 - 50m ish... Would that be possible? What type of micropump mechanism are you specifying. Something like an Osmotic micropump? and how could i possibly get the RFID to activate it?

Lol, no super villain plot. Hmm.. could you explain your idea to me a bit more? I am not very good with electronics, and am not quite sure how your idea would work...

I think you may have misunderstood the goal of the micro waves. They are in sealed inside the bracelet. The microwaves are only in place to break the capsule, not to remotely activate the mechanism. Also, could you please elaborate a bit on the RFID, and perhaps say where i could buy it?

Hi All, So i have to do a small engineering project, and i am wondering how to generate micro-waves. The goal of our project is to design a bracelet that can remotely activated to break a gelatin capsule embedded inside the capsule and will release a sedative (which will be absorbed through...
