超级电容在能源回收的应用

• Energy harvesting is the process by which energy is derived from external sources (e.g.,

solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured,

and stored. Energy harvesters currently do not produce sufficient energy to perform mechanical work, but instead provide very small amount of power for powering low-energy electronics.

• Powercast RF Energy Harvesting Module This wireless power module combines

Powercast's RF energy-harvesting technology with a supercapacitor to create a perpetual, battery-free power source for the wireless sensors commonly used in security,

environmental and condition-monitoring systems. The module integrates a power receiving antenna, a Powercast Powerharvester to convert the radio waves into low DC power and a supercapacitor. The supercapacitor stores the harvested energy and provides peak transmission power to a wireless sensor/transmitter board such as the Texas Instruments eZ430-RF2500T.

• Perpetuum's PMG17 vibration energy-harvesting micro-generator, together with a

supercapacitor, allow wireless sensor system manufacturers to design battery-free

condition monitoring systems that collect and report data on machinery for improved asset management. The PMG17 microgenerator converts unused mechanical vibration into a low but steady source of electrical energy. The supercapacitor then stores the energy and delivers the peak power needed to transmit sensor condition data over wireless networks such as IEEE 802.15.4 (Zigbee) and 802.11 (WLAN). Together they can power wireless sensor nodes indefinitely.
