　　通过脉冲能量收集供电电路

　　脉冲能量采集应用程序将能量脉冲转换为足够的功率，用于操作诸如无线开关、无线数据记录器、远程控制等简单电路。建立这些设计，工程师可以利用各种可用的超低功耗集成电路和能源生产商包括EnOcean，线性技术，Linx技术，集成，测试专业，芯片技术，美迪科技、罗姆半导体、Schurter、Silicon Labs的换能器，德克萨斯文书，其中。

　　能量收集应用程序通常依赖于清除流能量从身体发热，振动，或周围的RF一方面或从能源如太阳能、风能提取功率、等。在这种情况下，获得持续的能源，无论是低或高能量，通常可以确保连续或接近连续运行的电路。

　　Pulse harvesting， however， draws power from bursts of energy associated with a button push， sudden vibration， or other short-lived energy source. Outside of the pulse event itself， this approach leaves circuits with no additional power source beyond what excess energy they can store from pulse events. Despite these challenges， engineers have applied this approach to applications ranging from basic momentary pushbutton switches to complex wireless monitoring systems powered by the high-energy vibrations of railroad car wheels running across its tracks.
