The attached link expresses the electricity in watts. The watt is equivalent to 1 joule/ second. Joules are a unit of work or energy. http: //

The article breaks down the total amount of electrical energy in the human body as 11,000 watt hours. The electricity is also expressed in "usable terms". A sleeping person can produce 81 watts, a soldier standing at ease can produce 121 watts. The important consideration here is how to capture this electricity. Unfortunately, there is not a truly efficient way to do this.

A couple of interesting electrical measurements done on the human body are the EKG (electrocardiogram) and the EEG (electroencephalogram), which measure electrical activity in the heart and brain, respectively.
