Although electronics keep getting
smaller, cell phones can't really get
much smaller and still have a usable
keypad, much less be comfortable to
use and difficult to mislay.
This would be a phone with the
keypad and antenna integrated into a
slap bracelet like those that were
in the 1980's.
(For the uninitiated, this is a
chunk of fairly stiff material that (like
a tape measure) seeks either a long,
flat, concave shape or a curled-up
shape. So you "slap" it against
your wrist to put it on)
There would be a small rigid section
in the middle that would house the
display, chips, and battery. The
microphone would be at one end
(with the keypad buttons above), and
a small speaker would be at the other
The phone could double as a digital
watch when on your wrist.

Phone or watch? Oh yes, it's a phone - watches are smaller. [wagster, Aug 31 2005]

||Makes sense but could they really make phones this small? All for it if it's possible.
||I believe they can if you're willing to forgo the screen. I remember reading an article on disposable mobiles. They were very thin and credit card shaped, but didnt have any particularly useful features, no memory etc. Battery life would be a problem I imagine as well, assuming you wanted this to be rechargeable and offer a practical amount of talk time.
||Plus for the concept. I share the doubts about the execution but nice idea.
||Piezoelectric inserts. Deforming the bracelet to or from your wrist (as was THE thing to do in the 80s, constantly, over and over and OVER AND OVER.....) would power a small set of cells within the edge of the device.
||Could it be voice activated? A docking station could provide the means to add in your address book and link the phone numbers to voice commands.
||It could be a blue tooth headset with the main unit in your pocket or backpack. I like it because the grasp you use to take off a bracelet is the same one you use to hold a phone, so no shifting of your hand to answer the phone, just one smooth motion. would battery life be a problem if a head set is not being charged by the main unit?
||Kamathlin - don't go near any radiation
while you're wearing your phone.
||Basepair - *Mobile phones* are the source of radiations.
||I worked on a demo for a watch phone a few years back, I'll see if I can link to it.
||Ah, there we go - maybe a little bulkier than you were hoping for, but a wrist phone nonetheless.
