In this embodiment, considering that the temperature difference between the external environment temperature and the human body temperature cannot be always in one situation, a circuit as shown in fig. 21 is designed, in which the left side thermoelectric conversion device is a simplified left battery cell 4-1, the right side thermoelectric conversion device is a simplified right battery cell 4-1, C is an electric storage device, R is various electric devices in the sensing module, and each of the temperature switch a and the temperature switch B has two temperature sensing probes 1 and 2, wherein 1 is to detect the temperature of the external environment and 2 is to detect the temperature of the human body, for the temperature switch a, when the temperature measured by a1 is greater than or equal to the temperature measured by a1, a is off, when the temperature measured by a1 is less than the temperature measured by a1, a is on, for the temperature switch B, when the temperature measured by B1 is less than or equal to the temperature measured by B1, B is off, when the temperature measured by B1 is less than the temperature measured by B1, and B, closing. The left power supply is connected with the temperature switch A in series and then connected with C, R in parallel, the right power supply is connected with the temperature switch B in series and then connected with C, R in parallel, and the circuit is explained by three conditions according to the actual conditions that the vest is always in a working state and the external environment and the temperature of a human body are combined:
(1) when the ambient temperature is higher than the temperature of the human body, A1 is greater than A2, and the A temperature switch is turned off. B1> B2, B temperature switch closed. The right side heat-electricity conversion device works to supply energy to various electricity-requiring devices in the vest on one hand and store energy in the electricity storage device C on the other hand;
(2) when the ambient temperature is less than the human body temperature, A1< A2, the A temperature switch is closed. B1< B2, B temperature switch off. The left side heat-electricity conversion device works to supply energy to various electricity-requiring devices in the vest on one hand and store energy in the electricity storage device C on the other hand;
(3) when the ambient temperature is equal to the human body temperature, a1 ═ a2, and the a temperature switch is turned off. B1 ═ B2, the B temperature switch was off. The left and right side heat-electricity conversion devices do not work, and the electricity storage device C supplies energy to various electricity-requiring devices in the vest.
The voltage generated by the thermo-electric conversion can be calculated by the following formula:
U＝S(Th-Tc)
wherein U represents the thermoelectromotive force, S represents the sum of Seebeck coefficients of the two conductors, depending on the material chosen for the N-type and P-type semiconductors, and ThRepresenting the temperature value, T, of the high-temperature heat sourcecRepresenting the low temperature heat source temperature value.

Wherein n is the number of the (a) form or (b) form units in the integrated battery device. The difference between the ambient temperature and the human body temperature does not change much. For this reason, the present embodiment increases the number of n as much as possible to increase the total voltage U of the integrated batteryGeneral assembly。
The left battery unit 4-1 and the right battery unit 4-2 can also adopt a dynamic-electric conversion device to convert the biological kinetic energy of the user into electric energy. The device mainly comprises a metal coating on a flexible insulating pipe and a metal coating flexible insulating pipe covered by the treated polydimethylsiloxane. The metal coatings on the two flexible insulating pipes are respectively used as two electrodes of the device. Among them, copper, gold, or the like having excellent conductivity can be used as the metal. The flexible insulating pipe adopts ethylene-vinyl acetate copolymer and the like. The treated polydimethylsiloxane can enable the polydimethylsiloxane to easily adsorb negative charges to pair the two flexible insulating pipes, in order to clarify the working mechanism of the flexible insulating pipes, the working process can be simplified, the two flexible insulating pipes can move relatively, the metal electrode and the polydimethylsiloxane can be in contact separation action, and the electrodes on the two flexible insulating pipes can directly generate charge movement based on the coupling effect of contact electrification and electrostatic induction. The principle is shown in fig. 22:
in the original state (a), the polydimethylsiloxane surface is filled with negative electrostatic charges, and the metal electrode 1 generates positive charges; when there is external kinetic energy to press the two flexible insulating tubes, the gap between the metal electrode 2 and the polydimethylsiloxane shrinks due to electrostatic induction, resulting in accumulation of induced positive charges in the metal electrode 2, as shown in (b). Therefore, free electrons in the metal electrode 2 will flow to the metal electrode 1 for field balancing. This process produces a transient positive current. It is to be noted that even if the metal electrode 2 is brought into contact, the charge on the polydimethylsiloxane is not extinguished because the electrostatic charge is naturally immersed in the insulator polydimethylsiloxane as shown in (c). In case of re-separation of the two flexible insulating tubes, as shown in (d), the metal electrodes 1 and 2 will be restored to the original state (1). A transient negative current may be generated. Therefore, the two flexible insulating pipes can convert kinetic energy into electric energy in the contact separation process.
