Lock portion with piezo-electric actuator and anti-tamper circuit

1. An electronic lock, comprising:

a piezo-electric actuator positioned in a plug of a rotatable core, wherein the piezo-electric actuator has a first position and a second position and is configured to resist movement of a locking member during a non-normal unlocking operation of the electronic lock, wherein the locking member is at least partially positioned within a recess of the plug, and the piezo-electric actuator is in the first position when the electronic lock is locked and in the second position when the electronic lock is unlocked; and

tamper circuitry coupled with a connector of the piezo-electric actuator wherein the tamper circuitry is configured to resist an externally induced acceleration of the electronic lock by shunting electrical power produced by a resultant externally induced motion of the piezo-electric actuator back to the piezo-electric actuator such that the piezo-electric actuator bends toward the first position.

2. The electronic lock of claim 1 , wherein the tamper circuitry is configured to collect a voltage created when the piezo-electric actuator moves in response to the externally induced acceleration.

3. The electronic lock of claim 2 , wherein the tamper circuitry is further configured to shunt the collected voltage back into the piezo-electric actuator to resist a further movement of the piezo-electric actuator that could cause the electronic lock to unlock.

4. The electronic lock of claim 1 , wherein the tamper circuitry a resistor circuit.

5. The electronic lock of claim 1 , wherein the tamper circuitry is a resistor-inductor circuit.
