Technical notes
Mechanical envelope
A ring offers a narrow, curved volume rather than a conventional flat board area. The study considers component placement in relation to that envelope and the space available around the wearer’s finger.
Rigid-flex concept
The PCB concept uses the ring geometry to organise the electronics. Rigid component regions and their connecting sections are considered together with enclosure shape, rather than resolving the circuit and mechanical package independently.
Board and enclosure fit
The CAD study shows the proposed board and enclosure arrangement. It examines the geometry and placement choices that shape later electrical and mechanical development.
