Bioresorbable Device for Neural Injury Repair

Prof. Huinan Liu and her colleagues at the University of California, Riverside have developed a method for incorporating magnesium (Mg) microwires into nerve guidance conduits (NGCs) to improve neural healing. Mg-based microwires are naturally biodegradable and bioresorbable in the body, mechanically strong, and electrically conductive for neural stimulation and controlled release of neuroprotective ions. This […]

2598 – A Latching Thermopneumatic Microvalve for Ultra-low Power Applications

Low power microvalve Bi-stable microvalve functionality Background Microvalves control fluid flow in fluidics systems, and have improved control in applications where the significant power demands of a macro-scale valve would not be suitable. While microvalves offer unique advantages over their larger counterparts, such as decreased dead volume that allow faster response times, there is room […]

2559 – Power Divider-Phase Shifter Circuit

Extended resonance based phased array system Compact circuit structure High dividing/combining efficiency (>90%) Background A phased array is a group of antennas in which the relative phases of the respective signals feeding the antennas are varied in such a way that the effective radiation pattern of the array is reinforced in a desired direction and […]

2554 – Double-Clad Fiber Scanning Microscope

Double-clad fiber based scanning confocal microscope Optical fiber beam scanning Background Laser scanning confocal microscope was developed into a practical instrument in the late 1980s, where beam scanning was controlled by two galvanometer mirrors that are imaged onto the entrance pupil of an objective lens. Thus, only the direction of the incident excitation light rays […]

2525 – Frequency Shift Keying Demodulation Methods for Wireless Biomedical Implants

FSK demodulation methods for biomedical implants Less susceptible to the coupled coil misalignment and motion artifacts Background Wireless transfer of power and data is often achieved via inductive link between two magnetically-coupled coils. One application which requires transfer of large amounts of data to interface with many conduits include biomedical implants such as for cochlear […]

2503 – A Micromachined Pump for On-Chip Vacuum

Micromachined pump for on-chip vacuum High thermal isolation between pump and rest of the chip Background There is growing interest in relying on micromachined systems for gas-handling applications. Current limitations to the adoption of this technology stem from device operation at high temperatures, thus requiring thermal isolation in addition to vacuum-sealed lead transfer and low […]
