University of Washington researchers have invented a cellphone that requires no batteries -- a major leap forward in moving beyond chargers, cords and dying phones. Instead, the phone harvests the few microwatts of power it requires from either ambient radio signals or light. Source ~ http://www.sciencedaily.com/releases/2017/07/170705164453.htm I've been saying for years that someone should invent electrical devices that run on the electron charge from the atoms that construct the device. Looks like we are progressing towards that very thing. The new technology is detailed in a paper published July 1 in the Proceedings of the Association for Computing Machinery on Interactive, Mobile, Wearable and Ubiquitous Technologies. the battery-free cellphone takes advantage of tiny vibrations in a phone's microphone or speaker that occur when a person is talking into a phone or listening to a call. "The proof of concept we've developed is exciting today, and we think it could impact everyday devices in the future." The battery-free phone does still require a small amount of energy to perform some operations. The prototype has a power budget of 3.5 microwatts. Next, the research team plans to focus on improving the battery-free phone's operating range and encrypting conversations to make them secure. The team is also working to stream video over a battery-free cellphone and add a visual display feature to the phone using low-power E-ink screens. |

This is actually one of the goals of developing room temperature superconductors, as I understand it. Also part of this, is developing batteries that have a low threshold for receiving and holding a charge.

This is actually one of the goals of developing room temperature superconductors, as I understand it. Also part of this, is developing batteries that have a low threshold for receiving and holding a charge. I have seen a lot of new articles in the science and technology feeds I RSS. A few headlines from my Science Daily RSS feed: Thinking thin brings new layering and thermal abilities to the semiconductor industry In a breakthrough for the semiconductor industry, researchers demonstrate a new layer transfer technique http://www.sciencedaily.com/releases/2017/07/170711112418.htm ~ dated July 11, 2017 High-precision control of printed electronics Ferroelectric polarization induces electronic nonlinearity in ion-doped conducting polymers http://www.sciencedaily.com/releases/2017/07/170705104111.htm Date: July 5, 2017 Nickel for thought: Compound shows potential for high-temperature superconductivity http://www.sciencedaily.com/releases/2017/06/170617073638.htm Date: June 17, 2017 It seems there has been many different advances and break-thrus in the electronics and tech fields lately. These are merely one of many sources. There is even articles related to harnessing certain aspects of electron spins. Right in line with my hope for a device powered by its own atoms. Spinning electrons open the door to future hybrid electronics http://www.sciencedaily.com/releases/2017/06/170630105028.htm Date: June 30, 2017 Source: Linköping University Summary: A discovery of how to control and transfer spinning electrons paves the way for novel hybrid devices that could outperform existing semiconductor electronics. Researchers have demonstrated how to combine a commonly used semiconductor with a topological insulator, a recently discovered state of matter with unique electrical properties. If that technology comes to pass, there will be no need for any conductors. That means no batteries, no wires, no plugs, no circuitry. Eventually, no need for power generation facilities at all. Try to imagine the freedom that would bring. Devices could be a lot smaller and lighter as well. Not to mention the heat signatures or the environmental impacts. |

They were doing this thousands of years ago in Egypt.
