1. Re-layout of core components to achieve compact design
2. Solar charging is adopted because of the trouble of charging different objects.
3. The display is basically useless, so only the LED indicator is left.
4. The long strip of the patch can be pasted on a narrower surface, and the vision is also thinner.
5. Flexible design and flexible solar panel are adopted as a whole because they may be attached to the curved surface.
6. Considering different purposes, the patch can be switched between pendant and paste modes
