BackgroundSelf-powered remote-controlled systems are frequently powered via batteries or fuel cells, or by drawing energy from ambient sources such as heat or light. Energy scavenging has recently become popular owing to its ability to produce clean power for sustained period of time. Among various energy scavenging sources, vibration has gained attention due to its abundance and several suitable scavenging techniques. While many of the traditional methods have b…

BackgroundKelvin probes provide non-contact measurements of variations of surface potential. This tool can be used to map either of the two components contributing to surface potentials one due to work function and another due to trapped charge. Charge distribution on the wall acquired during manufacturing or in routine operation, can impact the function and behavior of the fluid in the channel. For example, it has been linked to cell adhesion and clotting of red b…

BackgroundScanning thermal microscopy is a high resolution scanning microscopy technique, which can map material topography, thermal conductivity and capacity, and temperature. As with other scanning microscopy techniques such as atomic force microscopy, the contact force is measured via deflection of the tip at the end of the cantilever. While powerful, the scanning microscopy techniques suffer from low throughput. Efforts to increase scanning speed have been me…

BackgroundMicrovalves 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 for improvement in both power consumption and response time, as well as other valve performance parameters and fabrication consider…

BackgroundLaser 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 is deviated at the entrance plane, while the pupil remains fully illuminated throughout the scanning. Accordingly, the focus spot of the laser beam out of the objective scans a…

BackgroundWireless 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 implants and visual prostheses. For such applications, increased rate of data transfer and minimal power consumption are paramount to successful operation of the device. To date, amplitude shift key…

BackgroundA 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 suppressed in undesired directions. Phased arrays are extensively used in satellite communications, multipoint communications, radar systems, early warning and missile defense systems, etc., so they are employed in large quantitie…

BackgroundThere 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 parasitic capacitance.Technology DescriptionResearchers at the University of Michigan have developed improved micromachined devices including a pac…

This technology demonstrates for the first time the interaction of Rheb and Rag GTPases to regulate mTORC1. Both GTPases are upregulated in a double knockout mouse model resulting in severe liver disease. This model shows synergistic interaction of these proteins and can be a useful model in studying liver disease.
