Hardware

Hardware covers the physical devices that sense movement and physiology, and the constraints that shape them. From wearables on the wrist to sensors embedded in gear, the trackers worn on the body, and the gateways that move data off all of them, the physics of sensing and the limits of power and durability set what is possible long before any software runs. Material here is descriptive and informational rather than a buying guide. Use the sections to understand the device classes and their trade offs, then visit a technology profile for specifics.

Hardware

Wearable Devices

Watches, bands, and chest straps worn on the body, where comfort, battery, and placement decide what can be measured. The most familiar form factor, and the one where the trade between endurance and capability is most visible.

Hardware

Sensors & Trackers

The sensing elements themselves and the small trackers built around them: optical, inertial, satellite, and physiological. The components that turn a physical quantity into a signal, each with its own strengths and failure modes.

Hardware

Instrumented Gear

Sensing embedded into equipment and apparel: balls, bats, boards, and garments that capture signals at the source. Powerful new metrics, paired with durability and calibration problems unique to objects that are struck and worn.

Hardware

Gateways & Edge

The devices that aggregate nearby sensors and process data before it reaches the internet: edge gateways and on site nodes. Where privacy, latency, and reliability are won or lost, between the sensor and the cloud.
