#The3rdInnovationContest#Composite human body generator - uninterruptible power supply system for smart wearable devices

1. Introduction of the Work
For example, it may include but is not limited to the following:
1. The appearance of the whole machine or the welded and assembled PCBA of the work;
    
2. The research background, purpose, function and market application prospects of the work;
Research background:
    Smart wearable products are increasingly entering people's daily lives, and the types and types of products are countless. However, the supporting foundation-the power system has developed slowly. At present, many companies are committed to the research of high-density batteries and fast charging technologies, and some companies are even committed to the promotion of shared mobile power supplies and shared charging stations. This project takes a different approach and introduces the concept of self-generated power supply by the human body and the environment, in the hope of solving the power supply problem of the increasing number of smart wearable devices.
Purpose:
1. Low-power smart wearable products, which can achieve no need for external chargers and generate enough power for their own use. Such as smart bracelets, etc. (The power generation of some specific groups is also insufficient, such as patients who are bedridden for a long time)
2. High-power smart wearable products, which can achieve more than 3 times the battery life. In case the battery runs out of power and the system shuts down, it can generate enough power within 100 minutes (in certain environments, the time is longer, such as in water, when sleeping, etc.) to restart the system. Such as GPS watches, some phone watches, etc.
3. Act as a mobile generator, power other peripheral devices through the USB port, with power bank and lighting functions.
Function:
   After this product is used, it generates power almost every moment. Different people generate different amounts of power, and different wearable products use different amounts of power. As long as the power generation is greater than the power consumption, uninterrupted power supply can be achieved (low power consumption products). Even if the power consumption is greater than the power generation (high power consumption products), the original equipment can be extended by more than 3 times the battery life, or after the power is exhausted, it can be restarted by self-generation.
Market application prospects:
  When used with smart bracelets, phone watches, human body data collection, wearable medical equipment, etc., it can revolutionize the power supply, thereby greatly changing the overall design. It has a very broad market application prospect.
3. What highlights can be reflected in the work in terms of innovation, fun, practicality and even public welfare?
Innovation:
  There is no similar or similar bar on the earth at present.
Interesting:
  You can experiment with the power generation of human daily movement and the surrounding natural environment. Reserve other power generation interface inputs.
Practicality:
  You can use the energy of the human body and nature to generate electricity for smart wearable devices. Even in the worst case (such as putting this product in a suitcase to isolate the human body from nature), it can also be used as a power bank and a flashlight.
When used as a power bank, depending on the matching with different devices, it is equivalent to carrying 4 to 7 batteries of smart wearable devices. It can also charge external smartphones. In the wild, even if the battery is used as a power bank and it is out of power, you can carry it on your hand to generate electricity to charge the battery. After a period of time, you have electricity to turn on your mobile phone or GPS and other devices.
Public welfare and others:
 It has important environmental significance and uses the energy of the human body and nature to generate electricity. Energy saving and environmental protection. It is highly practical and has broad market prospects.

. Summary
, such as your experience in completing the work, technical problems or debugging experience encountered, future plans for the work, and suggestions and opinions for our organizers. Some experiences, technical
problems or debugging experience encountered in the process of the work:
 The selection of devices is very important, and low-voltage devices are too difficult to find.
Future plans for the work:
 1. Continue to improve and improve the design (mainly to improve the mechanical structure to increase power generation and make it more humane, and the circuit-related conversion efficiency must be further improved),
 2. Find investors, open molds, directly compatible with Apple IWATCH (there is already a design plan), patent, and go on the market.
Suggestions and opinions:
None. Very good!
