Patent ID: 7243544

Claim:
An acceleration sensor, comprising: an acoustic wave device including a plate that functions as a propagation medium and at least one Interdigital transducer configured upon said plate; and an antenna integrated with said acoustic wave device, wherein said antenna communicates with said at least one interdigital transducer such that said antenna receives and transmits signals indicative of acceleration data, wherein said acoustic wave device is clamped at one end of said plate to an object under an acceleration wherein said plate is positioned such that said plate is perpendicular to said acceleration and submitted to a force at said free end of said plate; and an inertial mass fixed to said plate such that when said acceleration is applied to said acoustic wave device perpendicularly to said plate, said acceleration is converted to a proportional force through utilization of said inertial mass, thereby generating signals indicative of said acceleration data for wireless transmission from said antenna.
