Description

Self-powered LED band

The present invention relates to a wearable band, and more particularly, to a wearable band capable of driving an LED using electric power generated through triboelectric charging and allowing a microcurrent to flow through the wearer's skin.

Due to the busy daily life, the so-called Napots who have various leisure sports activities at night are gradually increasing. On the other hand, in case of exercising at night, various LED products are being developed that can inform others of their location in order to prepare for this, as the risk of collision with other people or traffic accidents is very high.

Since most of these LED products use a separate battery or a battery to drive the LED, there is a problem in that it cannot function as a device for identifying a wearer when a power source is discharged during night exercise.

Referring to Figure 5, the LED band (10, 20) and the LED band (10, 20) included in the contact power generator 200 is worn by the wearer when the wearer moves while receiving physical stimulation according to the movement . When the contact charging power generator 200 receives a physical stimulus, the housing 210 is positively charged and the contact charging powder 250 is negatively charged.

In addition, the contact charge powder 250 included in the inner space of the housing 210 is directed toward the upper electrode or the lower electrode among the pair of electrodes 230a and 230b according to the physical stimulus. At this time, when the contact charge powder 250 moves to the upper electrode, a potential difference occurs between the upper electrode and the lower electrode as the negative charge of the lower electrode screened by the negative charge of the contact charge powder 250 decreases. In order to create an equilibrium state, electrons move from the upper electrode to the lower electrode to generate current.

Next, when the contact charge powder 250 moved to the upper electrode moves back to the lower electrode by physical stimulation, the potential difference occurs again as the negative charge of the contact charge powder 250 decreases and the positive charge of the upper electrode screened. The electrons move from the lower electrode to the upper electrode to create an equilibrium state again, and current is generated.

As described above, at least one contact charging power generator 200 generates electric power by physical stimulation according to the movement of the wearer, and transmits it to the LED driver 300 and the micro-current electrode 400, respectively.
