Sony’s wireless electricity offering

In August hackaday covered a wireless electricity presentation from the TED conference. Now Sony has put out a press release on their wireless flat panel television prototype. The device is capable of operating without audio, video, or power cables connected to it. This is possible at distances up to 50cm at efficiencies as high as 80%.

As was talked about in the comments of the other article, the efficiency compared to that of a cable doesn’t blow our socks off. But this does show mainstream development of this technology. We hope to see advances in both efficiency and distance. We also look forward to that small black box (which we presume facilitates the energy transfer) being integrated into the TV’s body.

Microcontrollers can run without a battery in energy-harvesting systems

Sunday, June 29th, 2008

The low-power microcontroller market is really heating up (figuratively speaking). The latest entry comes from Texas Instruments, which is releasing some new members of its MSP430 family, namely the MSP430F5xx.

The company is claiming to offer the industry’s lowest power consumption for devices that can provide up to 25-MHz peak performance, increased amounts of embedded flash memory and RAM, and integrated peripherals, such as USB and LCD interfaces.

The intelligent digital and analog peripherals consume no power when not in operation. A high-resolution timer enables applications like voice-activated home security systems. Up to 1 Mbyte of linear memory mapping enables robust user interfaces, as well as applications for ZigBee and other low-power RF sensor networks.
