Abstract: A tamper resistant device comprises a matrix material and a microcapsule in the matrix material. The microcapsule has a first compartment, a second compartment, and an isolating structure separating the first and second compartments. The isolating structure is rupturable in response to a stimulus, such as temperature increases or compressive forces. The first compartment contains a first component, and the second compartment contains a second component. The first and second components react exothermically (produce heat) when in contact with each other. Thus, in some examples, a temperature change in the device resulting from the rupture of the isolating structure in the microcapsule due to physical tampering efforts can be used to trigger a security response.

Abstract: An apparatus is provided with a component configured with an interface comprising a resilient material. In a first state, the component is mechanically and/or electrically attached to a substrate. Exposure of the interface to the temperature that meets or exceeds the transition temperature of interface causes the resilient material to undergo a state change. The state change of the interface alters the position of the component, including separation of the component from the substrate. The separation disrupts the attachment thereby mitigating damage to the substrate and/or component.
