    摘要： The invention relates to a microelectromechanical resonator device comprising a support structure and a semiconductor resonator plate doped to a doping concentration with an n-type doping agent and being capable of resonating in a width-extensional resonance mode. In addition, there is at least one anchor suspending the resonator plate to the support structure and an actuator for exciting the width-extensional resonance mode into the resonator plate. According to the invention, the resonator plate is doped to a doping concentration of 1.2*1020 cm−3 or more and has a shape which, in combination with said doping concentration and in said width-extensional resonance mode, provides the second order temperature coefficient of frequency (TCF2) to be 12 ppb/C2 or less at least at one temperature. Several practical implementations are presented.

    摘要： An apparatus for installation within a tire for a vehicle includes a flexible arm and a power generating element coupled to the flexible arm for generating electrical energy. One end of the flexible arm is coupled to a rim of the tire. The opposing end of the flexible arm is configured to be in contact with the inside tread surface of the tire. The flexible arm is capable of deformation in response to a variability of distance between the rim and the inside tread surface during rolling movement of the tire, and the power generating element generates the electrical energy in response to deformation of the flexible arm. The apparatus may be combined with a tire pressure sensor module as a system so as to provide electrical energy for powering the tire pressure sensor module.

    摘要： A piezoelectric thin film (1) is formed through sputtering and consists essentially of scandium aluminum nitride. The carbon atomic content is 2.5 at% or less. When producing the piezoelectric thin film (1), scandium and aluminum are sputtered simultaneously on a substrate (21) from a scandium aluminum alloy target material (10) having a carbon atomic content of 5 at% or less in an atmosphere where at least nitrogen gas exists. The sputtering may be conducted also by applying an ion beam (31) on an opposing surface of the alloy target material at an oblique angle. Moreover, aluminum and scandium may be also sputtered simultaneously on the substrate from an Sc target material and an Al target material. As a result, a piezoelectric thin film which exhibits excellent piezoelectric properties and a method for the same can be provided.
