Abstract
Aspects of this disclosure relate to detecting temperature based on movement of one or more particles within a container. The container includes a medium material. Mobility of the one or more particles in the medium material changes in response to a change in temperature.
Claims20
A method of temperature detection, the method comprising:
- providing an enclosure that contains particles in a medium material, wherein the particles are magnetically sensitive and/or electrically conductive;
- and
- detecting, using a sensor integrated with the enclosure and a measurement circuit integrated with the enclosure, an indication of temperature based on movement of the particles in the enclosure, wherein the sensor is configured to detect the particles.
A system with temperature detection, the system comprising:
- a container;
- medium material within the container, wherein a property of the medium material changes in response to a change in temperature;
- at least one particle within the container, wherein the at least one particle is magnetically sensitive and/or electrically conductive, and wherein mobility of the at least one particle in the container changes in association with a change in the property of the medium material;
- and
- a measurement circuit configured to detect an indication of temperature based on movement of the at least one particle within the container, wherein the measurement circuit is integrated with the container.
A method of temperature detection, the method comprising:
- providing an enclosure that contains particles in a medium material in a first phase;
- maintaining positions of the particles until temperature crosses a threshold at which the medium material changes phase from the first phase to a second phase, wherein the particles have a higher mobility in the second phase than in the first phase, and wherein the particles move based on the temperature crossing the threshold;
- and
- resetting the positions of the particles after temperature is detected based on particle movement.
