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: //www.space.com/businesstechnology/technology/body_power_011128-1.html
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.
