Method and apparatus for a temperature sensor for measuring peak temperatures

A method and apparatus for an irreversible temperature sensor for measuring a peak exposure temperature. The apparatus is fabricated by printing an admixture of conductive nanoparticles on a dielectric substrate to form a film. The film has an electrical resistance that is inversely proportional to the exposure temperature. The electrical resistance also irreversibly decreases as the exposure temperature of the film increases. A portion of the film is exposed to a pulse of electromagnetic energy sufficient to render it substantially more electrically conductive than the portion that was not exposed. In use, the peak exposure temperature is determined by measuring the electrical resistance of the non-altered portion of the film and the electrical resistance of the portion that was exposed to the pulse of electromagnetic energy, and subtracting the electrical resistance of the altered portion from the electrical resistance of the portion that was not altered, to provide a difference value. The peak exposure temperature is then be calculated as a function of the difference value.

Matrix-assisted energy conversion in nanostructured piezoelectric arrays

A nanoconverter is capable of directly generating electricity through a nanostructure embedded in a polymer layer experiencing differential thermal expansion in a stress transfer zone. High surface-to-volume ratio semiconductor nanowires or nanotubes (such as ZnO, silicon, carbon, etc.) are grown either aligned or substantially vertically aligned on a substrate. The resulting nanoforest is then embedded with the polymer layer, which transfers stress to the nanostructures in the stress transfer zone, thereby creating a nanostructure voltage output due to the piezoelectric effect acting on the nanostructure. Electrodes attached at both ends of the nanostructures generate output power at densities of ˜20 nW/cm 2 with heating temperatures of ˜65° C. Nanoconverters arrayed in a series parallel arrangement may be constructed in planar, stacked, or rolled arrays to supply power to nano- and micro-devices without use of external batteries.

Method and apparatus for measuring temperature

A method for measuring the temperature of a first material (10) comprises measuring a temperature-related characteristic of a microparticle of a second material (12) in thermal contact with the first material (10) and calculating the temperature of the first material (10) using the measured temperature-related characteristic of the microparticle of the second material (12). The microparticle of the second material (12) can be located on a surface (10a) of the first material (10) in point thermal contact with the surface (10a), thus enabling the measurement of the surface temperature of the first material (10) at the point of contact. An apparatus (14) for measuring the surface temperature of the first material (10) is also described.

A platform unit for combined sensing of pressure, temperature and humidity

Sensors incorporated into tire plies to detect reversible deformation and/or temperature changes

Tires formed of one or more tire plies are disclosed. In some implementations, tire plies may include a temperature sensor that may detect a temperature of a respective tire ply. The temperature sensor may include one or more split-ring resonators (SRRs), each having a resonance frequency that changes in response to one or more of a change in an elastomeric property or a change in the temperature of a respective one or more tire plies. In some aspects, the temperature sensor may include an electrically-conductive layer dielectrically separated from a respective one or more SRRs.

Device for a product temperature variation detection below a threshold value

The present invention relates to a device for monitoring a temperature variation undergone by a product, which detects a drop in temperature below a predetermined temperature threshold (T cs), comprising: a sealed casing (I) which defines a containment space (V), and a mixture contained, or containable, in said containment compartment (V) which comprises a liquid phase (S) and a solid (D) comprising metal particles having an average nanometric size comprised between 1 and 300 nm and a coating layer (R) of said particles. This coating (R) comprises an organic material and is configured in such a way that, in a configuration of use of the device at a first temperature (T1) greater than said threshold temperature (T cs), it allows the maintenance of the solid (D) in solution in said liquid phase (S), in which the particles are separated from each other, while at a crystallization temperature (T2) of said liquid phase (S), being said temperature (T2) equal to or lower than said threshold temperature (T cs), the coating layer (R) separates from the metal particles allowing an aggregation of the metal particles. The mixture undergoes an irreversible loss of optical properties, allowing the detection of undesired temperature variation.
