Plastic thermo-electrochemical ceils （thermocells） involving aqueous potassium ferricyanide/ferrocyanide electrolyte have been investigated as an alternative to conventional thermoelectrics for thermal energy harvesting. Plastic thermocells that consist of all pliable materials such as polyethylene terephthalate （PET）, fabrics, and wires are flexible enough to be wearable on the human body and to be wrapped around cylindrical shapes. The performance of the thermocells is enhanced by incorporating carbon nanotubes into activated carbon textiles, due to improved charge transfer at the interface. In cold weather conditions （a surrounding temperature of 5 ℃）, the thermocell generates a short-circuit current density of 0.39 A/m2 and maximum power density of 0.46 mW/m2 from body heat （temperature of 36℃）. For practical use, we have shown that the thermocell charges up a capacitor when worn on a T-shirt by a person. We also have demonstrated that the electrical energy generated from waste pipe heat using a serial array of the thermocells and voltage converters can power a typical commercial light emitting diode （LED）.

The aim of the present study was to investigate the effects of Fu Zi on changes in the body heat of *** clinically healthy dogs were divided into two groups:the control group(six dogs) and the experimental group(six dogs).The control group was made to ingest normal saline mixed with canned meat,while the experimental group was made to ingest the Fu Zi solution mixed with canned *** infrared thermographic system was used to determine the level of body heat generated by these *** areas include the dorsocranial,dorsocaudal,ventrocranial,and ventrocaudal regions at pretreatment and were determined at 10,20,30,50,90,120,240,and 360 minutes after treatment for each of these areas. The results showed a tendency toward increased body heat until 30 minutes after ingestion of the Fu Zi powder mixed with canned *** significant differences in the changes of body heat were detected at 360 minutes in the DCd regions,20 minutes in the VCr regions,and 30 minutes in the VCd regions between the experimental and control groups(pbody heat for at least six hours.
