温度感测器的输出讯号往往仅达到毫伏 (Millivolt),因此必须放大讯号并注意量测系统中的杂讯。选择正确的增益,将可弥补硬体中类比数位转换器 (ADC) 的输入限制。

声波能产生大约50毫伏的微弱电流。
The sound waves produced a mild electrical current of about 50 millivolts.
数千个细胞加起来可产生每厘米5毫伏的电场。
Thousands of cells combine to generate the 5 millivolts per centimeter electrical field the fish USES.
产生的能源应该至少与成本相当——远远多于50毫伏。
The amount of energy harvested would have to be significant to justify the cost — a whole lot more than 50 millivolts.
If you measured it for most cells it's about between -60 and -90 millivolts.
如果你测量一下的话,大部分细胞都在-60到-90毫伏之间
For this particular cell here it looks like it's about -75 millivolts, so the inside of the cell is a little bit more negative than the outside.
这个细胞的膜电位是-75毫伏,所以细胞内侧跟外侧比起来电势要低一些
