    Abstract: A process for manufacturing an optical system includes forming a first hydrophobic surface at a semiconductor substrate, providing a first drop of transparent material having a first shape on the first hydrophobic surface, and allowing the first drop to harden to form a first optical element having the first shape. The optical system may be a particle detector, and the process may optionally further include forming a light source at the semiconductor substrate configured to generate a light beam that passes through the first optical element and a cavity to a photodetector.

    Abstract: A device such as a dosimeter for detecting ionizing radiation, for example, X-ray radiation, in hospitals or the like. The device includes scintillator material configured to produce light as a result of radiation interacting with the scintillator material, and photoelectric conversion circuitry optically coupled to the scintillator material and configured to produce electrical signals via photoelectric conversion of light produced by the scintillator material. The device includes a plurality of photoelectric converters optically coupled with the scintillator material at spatially separated locations. The plurality of photoelectric converters thus produce respective electrical signals by photoelectric conversion of light produced by the scintillator material as a result of radiation interacting with the scintillator material. Improved energy linearity is thus facilitated while providing more efficient detection over the whole energy spectrum of radiation detected.

    Abstract: An inverse electrowetting harvesting and scavenging circuit includes a first substrate having first and second surfaces. An electrode is formed proximate the first surface and includes an insulating layer covering a surface of the electrode. An electromechanical systems device includes a moveable mass extending over the first surface of the first substrate that may be displaced relative to the first substrate in three dimensions responsive to external forces applied to the moveable mass. The movable mass includes a moveable electrode and a conductive fluid is positioned between the insulating layer of the electrode and the movable electrode. Energy harvesting and scavenging circuitry is electrically coupled to the moveable electrode and the other electrode and is configured to provide electrical energy responsive to electrical energy generated by the moveable electrode, conductive fluid and the electrode through the reverse electrowetting phenomena due to movement of the moveable electrode relative to the electrode and to the conductive fluid on top of the electrode.
