三種能源收集工具在提高能源效率方面是可行的

　　隨著能源成本的上升，電源制造商努力提高效率、減少熱量和降低電氣成本。而節(jié)約能源很重要，能量收集裝置，將能量從環(huán)境–太陽(yáng)能、熱能、風(fēng)能、鹽度梯度，和動(dòng)能轉(zhuǎn)化為電能并儲(chǔ)存起來(lái)–小，低能電子被證明對(duì)于許多應(yīng)用越來(lái)越可行。

　　能量收集裝置根據(jù)它們收集的能量的數(shù)量和類(lèi)型而有所不同。例如，從一個(gè)人的振動(dòng)和運(yùn)動(dòng)（即動(dòng)能）可以提供約4μW / cm2能從皮膚表面溫度差能源收獲（熱電能量）可以提供25瓦/厘米2μ。光伏能源–捕獲光–提供約10μW / cm2室內(nèi)照明和10毫瓦/厘米2室外。最大的機(jī)會(huì)可能是從工業(yè)中獲取能量。熱電能源創(chuàng)造了行業(yè)可以提供高達(dá)10毫瓦/厘米2和動(dòng)能可以提供高達(dá)100瓦/厘米2μ。

　　The eZ430-RF2500-SHE is a complete solar energy harvesting development kit from Texas Instruments to help create a perpetually powered wireless sensor network. Based on its ultra-low-power TI MSP430 microcontroller， the solar energy harvester module includes a high-efficiency solar panel optimized for operating indoors under low-intensity fluorescent light. This provides enough power to run a wireless sensor application with no additional batteries. Inputs are also available for external energy harvesters such as thermal， piezoelectric， or another solar panel. The kit includes a USB debugging interface and a battery pack with expansion board.
