Diffraction anomaly sensor having grating coated with protective dielectric layer

A method and apparatus for optically assaying a targeted substance in a sample using a diffraction anomaly grating sensor. The optical sensor has a diffraction grating coated with at least one dielectric layer such that the sensor is sensitized to interact with the targeted substance. Upon interaction, light incident upon the sensor at a particular angle propagates through the dielectric, thereby exhibiting a dip in zero-order reflectance. Advantages of the present invention include facilitating increased sensitivity while protecting the metal grating from tarnishing and degradation. The present invention also allows for the construction of sensors that are sensitized to a plurality of substances, thus eliminating the need for an operator to reconfigure the sensing system in order to assay different substances.

Ultrasonic transmitter and receiver systems and products using the same

A transceiver preferably embedded within a wearable security watch, PDA, or other device which achieves a variety of wireless ultrasonic and / or radio-frequency based functions, including digital identification and proximity and sensation monitoring of assets, individuals, pets, and the like. The portable or wearable device realizes these functions by periodically polling and receiving information tags within the transmitting distance of the device. The invention can help reduce the likelihood of the theft, loss, or misplacement by detecting that a tag associated with or attached to an entity has left an individual's proximity and sounding an alarm. The device can also assist individuals with sensory impairments, including persons who are deaf, diabetic, and the like, by detecting a tagged entity as it enters the space around an individual, or by detecting environmental stimuli, such as excessive heat in an individual's proximity or vital sign changes, and sounding an alarm.

Resonant optical cavities for high-sensitivity high-throughput biological sensors and methods

Biosensors including resonant optical cavities. The resonant optical cavities are shaped so as to generate whispering gallery modes, which increase the quality factors of the cavities and facilitate the detection of analytes in a sample with enhanced sensitivity. The sizes of the resonant optical cavities facilitate their use in biosensors that include arrays of sensing zones. Accordingly, the resonant optical cavities may be used in high-density sensing arrays that can be read in real-time and in parallel. Thus, the resonant optical cavities are useful for detecting small concentrations of samples in real-time and with high throughput. Different embodiments of the biosensors are also disclosed, as are methods for using the biosensors.

Cored piezoelectric fiber fabric

The invention relates to a fabric made of cored piezoelectric fibers by weaving or knitting. A plurality of cored piezoelectric fibers are parallelly woven or knitted along a same straight line or curved line direction, crosswise woven or knitted along different straight line or curved line directions, or woven or knitted to form knots extending in the straight line or curved line direction to form an area with the cored piezoelectric fibers, and the area with the cored piezoelectric fibers is woven or knitted with an area formed by weaving or knitting other textile fibers to form one or more layers of the fabric. Thus, the area with the cored piezoelectric fibers in the fabric can serve as a sensor or drive. Due to flexibility and foldability, the cored piezoelectric fiber fabric can be made into wearable structures such as gloves, vests, wrist bands, ankle pads, socks and the like which can be put on a living body or a robot body to serve as sensors for sensing health conditions in the living body, movements of the living body or the robot body or external acting forces; the wearable structures can also serve as drives for adding external signals onto the fabric, the living body can sense the external signals by sensing deformation, vibration and the like of the fabric; the wearable structures can further serve as sonic sensors or sonic drives to sense external sound waves or transmit sound waves.
