Pulse Ring
Like a mood ring, but flashes with pulse | |
This is both a biofeedback device and a fashion accessory. It's a watch-battery powered ring that changes color with every heartbeat. A cheesier implementation might use a flashing LED...
Why, you might ask: subtle way of letting the person you are with know that she excites/bores you, teaching
yourself how to relax by slowing your own pulse (try it sometimes with a pulse monitor), or seeing if you an sync your heartbeats with a bunch of friends...
Not for use while playing poker.
The heart beateth fast.

it also has a medical purpose. |

I like it, but what's the mechanism that's less-cheesey than an LED? |
|
| |
I assume the smoothie version pulses gradually brighter and then fading smoothly to dimmer, while the cheeesy one blinks abruptly on-off, [pig head]. [+] |
|
| |
I imagine the less-cheezy-then-LED mechanism would have to be some sort of electrochemical reaction that can affect a color change, or maybe even an LCD or E-ink type of system. But I was envisioning something that's translucent...so LCD or E-ink don't pass the "cheezy" test. Any ideas? |
|
| |
I think that given the versatility of LEDs, you'd be able to set several miniLEDs into translucent plastic and make them brighten and dim quite smoothly. |
|
| |
Which would look nicer that one big red LED set out in the open and blinking on and off. |
|
| |
I was just wondering of there was something new in mind for this. LEDs are likely the best bet, I'd say. |

What odd town do you live in [21q]? |

This would be a good indicator for use during cardiovascular exercise. [+] Like when you're running away from the hooligans that are trying to steal your blinky trinket. |
|
| |
A pretty popular item in the old folks home, I imagine... confirmation of a pulse would be cause for celebration! So, Bun! [+] But, on the other hand, this is one data collection point from a lie detector. So, Bone! [-] I think I'll stand over here and look creepy until your ring starts flashing faster... MUUHAHAHAHAAAAAA! |
|
| |
I think it be pretty, useful and ever so delightful. + |
|
| |
+ possible explosion after jogging... |
|
| |
It could sequence around the ring, once for every pulse, and pause on the main LED. |
|
| |
Extra points for powering it from the Seebeck effect. |
