摘要： A temperature sensor is described that includes a base, a first set of posts attached to the base having a first coefficient of thermal expansion, a second set of posts attached to the base and having a second coefficient of thermal expansion, and two substantially parallel conductive plates forming a capacitor. The first of the conductive plates is fixed to the first set of posts and the second of the conductive plates is fixed to the second set of posts. Temperature changes cause the first set of posts and the second set of posts to elongate at different rates, thereby changing a distance between the conductive plates and therefore the resulting capacitance. A system and method are also described for determining resonant frequency associated with the sensor which correlates to the temperature at the sensor when multiple sensors are networked across a system.

摘要： An illustrative embodiment of a temperature-activated voltage generator includes a generator housing having housing interior; a flexible, temperature-sensitive bimetallic element disposed in the housing interior; and a piezoelectric element carried by the generator housing. The bimetallic element is positional between first position wherein the bimetallic element disengages the piezoelectric element, and a second position wherein the bimetallic element engages the piezoelectric element. Electrical voltage output leads are electrically connected to the piezoelectric element. A voltage-generating method is also disclosed.

摘要： A broadband vibration energy harvesting apparatus and method. In one embodiment, a straight piezoelectric beam and a straight biasing beam are disposed parallel to one another and axially compressed by a support structure such that both of the beams are slightly bowed. This buckles and reduces the axial stiffness of both of the beams. The piezoelectric beam is secured to an external vibrating structure and supported by the structure. The flexing motion of the piezoelectric beam generates electrical signals that can be used to power a wide variety of devices. The apparatus is especially sensitive to small amplitude vibration signals and is able to harvest vibration energy over a wide range of frequencies, and is not limited to vibrations at discrete resonant frequencies. The apparatus is especially well suited for use in powering remotely located electrical sensors and actuators employed in automotive, aircraft and aerospace applications.

摘要： An energy harvesting apparatus and method that is especially well suited for harvesting low frequency broadband vibration energy from a vibrating structure is presented. The apparatus includes a pair of disc springs that are arranged in an opposing relationship. A threaded fastening member and a threaded nut extend through apertures in each of the disc springs and enable a predetermined preload force to be applied to the disc springs. The preload effectively “softens” the disc springs, thus heightening the sensitivity of the disc springs to low frequency, low amplitude vibration energy. A piezoelectric material ring is secured to each of the disc springs. Each piezoelectric material ring experiences changes in strain as its associated disc spring deflects in response to vibration energy experienced from a vibrating structure. The electrical output from each piezoelectric material ring can be used to power or activate various forms of electronic sensors and devices, or it can be conditioned and stored in a circuit for later use.
