Intercalated Graphene Layers for Charge Extraction and Enhanced Light Absorption

Quantum dots (QDs) have shown extraordinary optical properties based on their size-tunable band gap and low-processing cost that have allowed the realization of promising photodetectors and solar cells. However, the short diffusion length and mobility in QD films remains a main limitation and subject of intensive research as the key to improve the performance of QD based optoelectronic devices. A very innovative strategy to overcome the low mobility of QDs is to use them as sensitizer with high conductive systems such as graphene, 2D semiconductors and Si. The combination of graphene (Gr) and QD into a hybrid device splits the photoconversion/detection “tasks” between these two complementary nanomaterials: QDs absorb light and generate photocharges, while graphene takes care of charge collection for efficient transport.

Compact Voltage Sensor For Power-Lines

Power-lines for the distribution and transmission of high-voltage electricity are ubiquitous infrastructure of modern societies. Convenient means exists for measuring the currents in these power-lines. However measuring the voltages between conductors of power-lines is difficult and costly because it typically requires large and expensive equipment due to the high voltages (which can be tens or hundreds of thousands of volts). To address that situation, researchers at UC Berkeley have developed a novel, practical and inexpensive way to measure the conduct-to-conductor voltages of power-lines using components in just one conductor of overhead distribution and transmission power-lines. In addition to voltage, this technology can be augmented to measure current, power, and power flow directions. This Berkeley technology can also applied to power-lines in office buildings, factories and power substations.

Wireless Communication Using Magnetic Waves in the Human Body

Medical devices and wearable consumer products have fundamental anatomically-driven size constraints that necessitate small form factors. Since most patients and consumers desire long battery life, and battery volume is limited by anatomy, one of the only ways to increase lifetime is to reduce the power of the underlying circuits. The power consumption of wireless communication circuits is often large, and while power can be minimized by restricting the communication distance to just a few meters from sensor nodes to a personal base station as part of a body-area network (BAN), it can still dominate the overall energy budget of a wearable device. Current human body communication (HBC) systems communicate using capacitive electrodes that are placed on the body and generate electric fields that then have fringing currents that travel through conductive biological tissues (in one embodiment – galvanic coupling) or fringing fields that interact with the surrounding environment (in another embodiment – capacitive coupling). Both techniques have slightly better path loss than conventional far-field RF techniques, but suffer from electrode impedance variation, environmental variation, or both, making the design of ultra-low power HBC systems difficult. Establishing methods that improve path gain and thus reduced power consumption will aid the functionality of industry devices greatly. 

Novel Anti-Bacterial, Anti-Fungal Nanopillared Surface

Medical devices are susceptible to contamination by harmful microbes, such as bacteria and fungi, which form biofilms on device surfaces. These biofilms are often resistant to antibiotics and other current treatments, resulting in over 2 million people per year suffering from diseases related to these contaminating microbes. Death rates for many of these diseases are high, often exceeding 50%. Researchers at UCI have developed a novel anti-bacterial and anti-fungal biocomposite that incorporates a nanopillared surface structure that can be applied as a coating to medical devices.
