Range and reliability depend on the phone, body, environment, antenna and enclosure. Metal makes RF-transparent design essential.
Technology
Compact technology, openly explained.
A small metal object with a wireless connection requires careful engineering. We distinguish direction, targets and unvalidated performance.
Connection
Bluetooth Low Energy to the phone.
Energy
Several days is a target, not a promise.
Around seven days is a development target. Real performance depends on battery capacity, firmware, radio behaviour, temperature and ageing.
Enclosure
Comfort, water and radio must work together.
IP67 is a technical target. Only laboratory testing can support a final rating.
Software
App, firmware and operating system form one chain.
An early Android app exists. Jewellery firmware and a new iOS app will be developed in phases.
Validation
Testing and certification before claims.
Functional prototypes, radio, battery, EMC, material and applicable European product requirements will be part of development. Certification has not been completed.
