Wearable Health Hardware Design
Budget: $250 – $750 AUD
This project covers the full end-to-end hardware development of a compact health-monitoring wearable. The core electronic system must seamlessly integrate three critical blocks—biosensors, power-management circuitry, and a wireless connectivity module—onto a multilayer PCB small enough for a wrist-worn form factor.
Biosensing
• The design centres on a heart-rate monitor as the primary biosensor. Signal quality, noise immunity, and optimal placement on the board and inside the enclosure all have to be engineered with production-ready accuracy.
Power management
• Fast-charge capability and ultra-low standby consumption are non-negotiable. Battery chemistry, protection ICs, and charging topology should be selected and simulated so that typical daily usage still leaves ample reserve before the next charge cycle.
Connectivity & processing
• A Bluetooth Low Energy or comparable wireless SoC will stream data in real time to a companion mobile app. Antenna layout, impedance matching, and certification readiness must be addressed up front.
Mechanical integration
The electronics must mate cleanly with a lightweight enclosure that is comfortable on the wrist while still meeting drop, sweat, and ingress requirements. 3D CAD models should be ready for iterative SLA prints and later injection-mould tooling.
Deliverables
1. Complete schematic capture and multilayer PCB layout (native Altium, KiCad, or similar).
2. Bill of materials with manufacturer part numbers and lifecycle status.
3. 3D CAD assembly of the enclosure with board-to-housing alignment features.
4. DFM / DFA review package ready for handoff to a contract manufacturer, including assembly stack-ups and recommended test points.
5. Brief validation plan outlining lab tests for heart-rate accuracy, charge time, and power draw.
Prior work on wearables, consumer IoT, or health-tech hardware will help ensure the design meets both user comfort and regulatory expectations.
