Abstract: A device comprises a surface that is a hydrogel having a targeted mesh size that permits a low-speed friction coefficient near or lower that that typically reported for cartilage of 0.01 to 0.02, a transition. The device can be a contact lens to sit on the cornea where, during a blink, eyelid slides past the eye surface at about 100 mm s−1. The hydrodynamic lubrication of the hydrogel of the device separates the contact lens surface from the surfaces of the tarsal conjunctiva and marginal conjunctiva of the eyelid. Other devices that can comprise the hydrogel of a targeted mesh size are those that can contact cartilage of articulating joints.

Abstract: A tunable non-reciprocal frequency limiter with an asymmetric micro-electro-mechanical resonator has two independent transducer ports. One port has a film stack including a 10 nm hafnium zirconium oxide (HZO) and another port has a film stack including a 120 nm aluminum nitride (AlN) film. These film stacks are deposited on top of 70 nm single crystal silicon substrate applying CMOS compatible fabrication techniques. The asymmetric transducer architecture with dissimilar electromechanical coupling coefficients force the resonator into mechanical nonlinearity on actuation with transducer having larger coupling. A proof-of-concept electrically-coupled channel filter is demonstrated with two such asymmetric resonators at ˜253 MHz with individual Qres of ˜870 and a non-reciprocal transmission ratio (NTR) ˜16 dB and BW3dB of 0.25%.

Abstract: According to a method for using near infrared spectroscopy to detect compartment syndrome, an optics array is placed around a body region of a patient that contains a vulnerable compartment of tissue. The optics array includes emitters that generate photons at NIR wavelengths and detectors that detect photons at NIR wavelengths. Photons are emitted from at least one of the emitters, and detected at more than one of the detectors after those photons traveled through the tissues of the body region of the patient. A cross-sectional measure of regional differences in absorption within a cross-section of the body region of the patient is displayed so as to allow detection of compartment syndrome. The method is carried out with a device for using near infrared spectroscopy to detect compartment syndrome.

Abstract: Wireless power transmission (WPT) systems are provided. For example, the WPT system can use one or more power transmitting coils and a receiver for electromagnetically coupled wireless power transfer. The electrodynamic receiver can be in the form of an electrodynamic transducer where a magnet is allowed to oscillate near a receiving coil to induce a voltage in the receiving coil, a piezoelectric transducer where the magnet causes a vibrating structure with a piezoelectric layer to move, an electrostatic transducer where movement of the magnet causes a capacitor plate to move, or a combination thereof. An alternating magnetic field from the transmitting coil(s) excites the magnet in the receiver into mechanical resonance. The vibrating magnet then functions similar to an energy harvester to induce voltage/current on an internal coil, piezoelectric material, or variable capacitor. Embodiments utilize magnetic coupling and electromechanical resonance for safe, spatially distributed, low-frequency power delivery to portable devices.

Abstract: Various examples are provided for superlattice conductors. In one example, a planar conductor includes a plurality of stacked layers including copper thin film layers and nickel thin film layers, where adjacent copper thin film layers of the copper thin film layers are separated by a nickel thin film layer of the plurality of nickel thin film layers. In another example, a conductor includes a plurality of radially distributed layers including a non-ferromagnetic core; a nickel layer disposed about and encircling the non-ferromagnetic core; and a copper layer disposed on and encircling the nickel layer. In another example, a hybrid conductor includes a core; and a plurality of radially distributed layers disposed about a portion of an outer surface of the core, the plurality of radially distributed layers include alternating ferromagnetic and non-ferromagnetic layers. In other hybrid conductors, the radially distributed layers can utilize magnetic and non-magnetic materials.

Abstract: A method of detecting hardware Trojans in an IC includes providing a golden IC layout data set or SEM image data taken at long dwelling time on an active area of the golden IC after polishing it from the backside. Next, the IC under authentication (IUA) sample is prepared for fast SEM imagining (shorter dwelling time) after backside thinning. Next step is to perform image processing on the IUA's SEM image, which includes histogram equalization with noise filtering using Gaussian and Median filters. In the last step, the IUA sample data with the shorter dwelling time is compared with the golden IC layout data or the golden image data from high quality (longer dwelling time) SEM scanning process. At the end the result of the comparison is used to identify hardware Trojans.
