Abstract
The present invention provides electronic systems that include thin film thermal batteries incorporated in the electronic system to provide a security function.
Claims20
An electronic system comprising:
- a thin film thermal battery incorporated into the electronic system so that the thermal battery can activate in response to a triggering event indicative of a breach of security with respect to the electronic system;
- at least one microelectronic device incorporated into the electronic system;
- and
- a security circuit that can carry out a security operation with respect to the at least one microelectronic device, wherein at least a portion of the security operation is carried out using power supplied by the thermal battery.

An electronic system comprising:
- a thin film thermal battery incorporated into the electronic system so that the thermal battery can activate and output thermal energy in response to a triggering event indicative of a breach of security with respect to the electronic system;
- and
- at least one microelectronic device incorporated into the electronic system and positioned relative to the thermal battery so that thermal energy provided by the thermal battery in response to the triggering event can damage the microelectronic device.
A security system that can be used with an electronic system, comprising:
- a sensor that can generate an output in response to a triggering event detected by the sensor, the triggering event being indicative an unauthorized party attempting to access the electronic system;
- and
- a thermal battery electrically coupled to the sensor so that the battery can be initiated to provide a power output in response to the output of the sensor, wherein the power output of the thermal battery can be used to carry out at least one security operation.
A method of providing security for a microelectronic device, the method comprising the steps of:
- initiating a thin film thermal battery in response to a triggering event indicative of an attempt by an unauthorized entity to access the microelectronic device;
- and
- using power supplied by the thin film thermal battery to carry out at least one security operation with respect to the microelectronic device.
A method of providing security for a microelectronic device, the method comprising the steps of:
- causing a piezoelectric transducer to generate an electrical signal in response to a triggering event indicative of an attempt by an unauthorized entity to access the device;
- using the electrical signal of-the transducer to initiate a thin film thermal battery;
- and
- using power supplied by the thin film thermal battery to carry out at least one security operation with respect to the device.
