Self-Powered Pressure Sensor Assembly
First Claim
1. A pressure sensor assembly comprising:
- an accelerometer configured to produce a first current upon movement of the accelerometer;
a capacitor configured to receive the first current thereby charging the capacitor;
a gate element operably connected to the capacitor and configured to discharge a second current from the capacitor upon the capacitor attaining a threshold voltage;
a pressure sensor configured to receive the discharged current to produce a first signal corresponding to at least one pressure reading of the pressure sensor; and
a transmitter operably connected to the pressure sensor and configured to transmit a second signal based upon the first signal to an external device configured to store data corresponding to the second signal.
