Abstract: The invention detects massive particles, which are invisible to contemporary particle detectors employing electro-magnetic sensors. The apparatus contains a mechanical sensor detecting massive particles via their influence on mechanical motion of sensor constituent atoms causing changes in sensor characteristics. The apparatus may include said sensor made of crystal or condensed-matter attached as a bob at the end of a pendulum that starts swinging when massive particles hit it. The star-source emitting massive particles is located by finding a space direction from which the particles arrive and produce the changes in said sensor position and physical characteristics. Energy is harvested by using changes in sensor energetic characteristics including mechanical motion, electromagnetic potential, thermal or other reactions. The invented sensor has directly detected massive particles from the Sun, central region of our Galaxy, and the star Deneb. The average mass-energy of solar massive particles is 3.1?1+1.

Abstract: A multidomain plate acoustic wave device is provided having one or more single piezoelectric crystalline plates with differently polarized ferroelectric domains, where the domains have diverse directions of their axes of polarization. The device may consist of a multidomain plate acoustic wave transducer, a multidomain plate acoustic wave delay line, a multidomain plate acoustic wave rf filter, and any combination thereof. The differently polarized ferroelectric domains may comprise a collection of inversely or differently poled ferroelectric domains within a single piezoelectric medium. The medium may be any crystalline or ceramic plate with non-zero piezoelectric properties, in which the domains are created and embedded. In varying embodiments, the device includes electrodes oriented to generate an external rf field in various, respective directions, including in a direction normal to a basal plane of the device, or in a direction parallel to a length or a width of the device.
