New device captures ambient energy from the air to power small electronic devices

Energy3

Professor Manos Tentzeris displays an inkjet-printed rectifying antenna used to convert microwave energy to DC power.

Researchers have found a way to capture and harness energy transmitted by such sources as radio and television transmitters, cell phone networks and satellite communications systems. By getting this ambient energy from the air around us, the technique could provide a new way to power networks of wireless sensors, microprocessors and communications chips.

Nokia Developing A Cell Phone That Never Needs Recharging

Nokia Developing A Cell Phone That Never Needs Recharging

Nokia hopes to create a device that could harvest enough power to keep a cell phone topped up. 

A cell phone that never needs recharging might sound too good to be true, but Nokia says it’s developing technology that could draw enough power from ambient radio waves to keep a cell-phone handset topped up.

A Lamp That Adjusts To the Environment

A Lamp That Adjusts To the Environment 

 Stimuli 3.0

Here’s a design concept that shows some unusual thinking on the part of its creator, Chris Natt: What if you fitted a smart lamp with petals that open and close like a flower? The result is Stimuli 3.0, a shape-shifting device that measures ambient light and adjusts its illumination accordingly, using a three-axis gearbox.
