Power at Your FingerTIps
电池寿命仍然是任何便携式电子设备成功的关键因素。随着电池技术的不断发展,新功能不断地被添加到便携式设备中,从而对电力需求保持最大的压力。能量收集的作用只会变得更加重要,无论是增强电池功能,还是最终赋予权力自主权。
从环境中产生动力的能力,如机械开关、振动、热或光、转换、储存和随意使用,都有可能对便携式设备的实用性产生巨大的影响。触摸屏的下一个目标。
研究正在进行世界范围内的各种压电能量收集技术和新型纳米材料可能导致自供电的触摸屏。同时,太阳能电池可以说是目前最实用、最容易获得能源的解决方案,可用于触摸屏的供电。

This arTIcle will take a look ahead, projecTIng the outcome of some of the research currently underway, as well as review some of the solar cells currently available for charging batteries and/or powering touchscreen acTIvated portable devices. These will include the Ixolar family from IXYS (KXOB22-01X8, KXOB22-12X1) and the Amorton range (AM-1456CA, AM-5412CAR) from Sanyo Energy.
