膝盖发电英国研究人员最近研发了一种新型的发电装置,用人们走路时膝盖的活动来为随身携带的电子设备供电。目前研发出的原型装置的发电量约为2毫瓦,改进之后可超过30毫瓦,足以为心率监测器、电子计步器等随身携带的电子设备供电。如果今后能实用化并进 Knee Power Generation British researchers have recently developed a new type of power generation device that uses the activity of the knees while people are walking to power their portable electronic devices. The prototype device currently being developed has a power output of about 2 milliwatts, and can be upgraded to more than 30 milliwatts, enough to power electronic devices such as heart rate monitors and electronic pedometers. If practical in the future
