摘要:
A variable focal length microlens system having a base section with a fluid chamber and a fluid pressurization mechanism. A flexible, substantially transparent polymer lens section is fixed above the fluid chamber and the lens section has a curvature providing an initial focal point when in an unstrained state. The fluid chamber is substantially sealed and the fluid pressurization mechanism includes a flexible wall in the base section. The flexible wall may be displaced by magnetic activation, PZT activation of another activating mechanism.

A solar cell. The solar cell includes a substrate, a first layer comprising a first copper-based material deposited upon the substrate, the first copper-based material electrically attracted to the substrate or to a first optional deposit layer deposited between the substrate and the first layer, and a second layer comprising a second copper-based material deposited upon the first layer or an second optional deposit layer deposited between the first layer and the second layer, the second copper-based material electrically attracted to the first layer or to the second optional deposit layer, wherein the first copper-based material and the second copper-based material are selected from the group consisting of copper indium gallium (di)selenide (CIGS), copper indium selenium (CIS), and cadmium sulfate (CdS).
摘要:
A chipless RFID tag system having a transmitter sending an input signal and a tag substrate. The tag substrate has at least one microstrip and the microstrip has a first portion with a first impedance and a second portion with a second impedance different from the first impedance. The system further includes a receiver detecting at least two reflections from an interface of the first and second impedances and identifying relative time domain positions of the reflections to one another.

A biomedical sensor and sensor system for analysis of breath are disclosed. The biomedical sensor can include two layers arranged to swell or contract in a plane perpendicular to an axial direction while being restricted from swelling in the axial direction. The biomedical sensor includes resistance connections to allow measurement of the resistance of each layer and a combined resistance of both layers. The sensor system can include one, two, or three or more sensors, each having a pair of electrodes separated by a gap and one or more layers of composite material located within the gap. the sensor system includes resistance circuits configured to measure changes in resistance between the electrodes. A polypyrrole/polymethyl methacrylate/polyethylene glycol composite material and method of making the same are disclosed.
摘要:
Wireless sensor system that integrate sensors, wireless communication module, and user interface units are disclosed. The system can include sensors fabricated for identifying hypoglycemia in the breath of a patient. The system can provide a low-power and small form factor wireless sensor system that integrates multiple sensors (e.g. resistor and capacitor based) and includes an on-chip temperature sensor in an ASIC. The disclosed system collects information from the sensors and wirelessly transmits the processed information to end user interface units, such as smart phones. The systems can be used in healthcare applications, including un-interrupted involuntary continuous monitoring of vital parameters of human body or environment, and other applications, and can be particularly adapted to monitoring hypoglycemia.
