Child-Friendly Bluetooth Tracking Ring Prototype

I need assistance in developing a Bluetooth-enabled ring prototype that serves as a tracking device for children. My initial thought is to use resin or latex in crafting the ring.

Ideal skills and experience:

- Product development expertise
- Understanding of information technology, particularly Bluetooth technology
- Experience in working with child-friendly materials
- Understanding of how to integrate software or firmware into physical products

Main responsibilities:

- Take lead in building a prototype of the ring
- Consult, if necessary, with the company hired to write the firmware or software for the ring
- Ensure the ring’s design is appropriate for children.

Please note, the ring's Bluetooth connectivity range doesn't need to exceed the standard.
