Tire-mounted energy generator and monitor

This invention describes a system to monitor a tire's condition, like its pressure or temperature, without needing batteries. It generates its own electricity from the tire's rotation using a special device embedded within the tire's tread. This power then fuels the monitoring sensors, which are part of a single unit attached to the tire's interior.

Why it matters: Filed before significant advancements in flexible piezoelectric materials and ultra-low-power electronics. These improvements make reliable, continuous energy generation and sensor operation more feasible now.
