SmartBuds
They power up when you put them in your ear! | |
A small feature meant to save battery and keep ears free of obstruction when not in use. These bluetooth buds will answer a call when the right bud is put into the ear. The user may keep the left one in or put into a left pocket, but the buds will only power up and answer a call when the right one is
inserted in the ear.
Temperature?
Peltier powered

I've never used battery-powered buds, but the idea of using
temperature to turn them on sounds good. [+] |

Here's a blog from a guy trying to actually make thermoelectric ear buds which require no external power source. [link] |

Baked. If you look at Lt. Uhura's earpiece, you'll see it has a prominent finned portion. This is the external heatsink for the Seebeck-effect thermopile that powers it. |
|
| |
The unit activates automatically when inserted into an ear canal. |

That's different from the concept currently under discussion. |
|

[2fries], heat to electricity is the Seebeck or Thermocouple effect; the Peltier effect is the reverse - current to heat-pumping. |

Oh, I haven't looked up Pelttier yet.
I've only gotten as far as the D's in the Everythingictionary, but this guy specifically mentions using Peltier plates as a power source for ear buds. |

Peltier devices can be used "backwards" to generate electricalenergy. |
