A Micro/Nanobubble Oxygenated Solutions for Wound Healing and Tissue Preservation

Soft-tissue injuries and organ transplantation are common in modern combat scenarios.

Described here is a novel device capable of producing MNB solutions that can be used to preserve viability and function of such organs/tissue. Additionally, these solutions may be used with negative pressure wound therapy to heal soft-tissue wounds.

Self-Cleaning Mass Sensor For Particulate Matter Monitoring

Airborne particulates (such as vehicle exhaust, dust, and metallics) are a health hazard.  Monitors for measuring particulate matter (PM) concentrations in air are typically designed for stationary industrial use; and while they are quite sensitive, they are also bulky, heavy, and expensive.  Accordingly, there is a need for PM concentration monitors that are inexpensive and portable so that they can be more pervasive, and also used by mass-market consumers. Recently, various types of portable PM monitors have been developed.  One class of monitor uses optical technology to measure particulates flowing through (not deposited on) the device.  This optical technology is not sensitive to extremely small particles (with diameters of 200 nanometers or less), yet these small particles are a serious health hazard.  Another class of PM monitor uses various technologies to measure the mass of particles deposited on (not flowing through) the device.  This type of monitor can be quite sensitive, but eventually, it can become overloaded with deposited particles.  Moreover, multiple layers of particles can eliminate the possibility of determining the chemical nature of the particles. To address these shortcomings, researchers at UC Berkeley have developed a means of periodically cleaning deposited particles from mass-sensing components of deposit-based PM sensors.  The Berkeley technology results in PM sensors that are not only portable and low-cost, but also have long-lasting functionality.

Apparatus and Method for 2D-based Optoelectronic Imaging

The use of electric fields for signaling and manipulation is widespread, mediating systems spanning the action potentials of neuron and cardiac cells to battery technologies and lab-on-a-chip devices. Current FET- and dye-based techniques to detect electric field effects are systematically difficult to scale, costly, or perturbative. Researchers at the University of California Berkeley have developed an optical detection platform, based on the unique optoelectronic properties of two-dimensional materials that permits high-resolution imaging of electric fields, voltage, acidity, strain and bioelectric action potentials across a wide field-of-view.

Supermaneuverable Autonomous Swimmer

The most commonly used Autonomous underwater vehicles (AUVs) have shapes and structures similar to submarines and winged torpedoes, and maneuver using their fins, wings, stabilizers, and through changing the direction of their thrust vector. Existing systems have some disadvantages: (i) drag forces and torques exerted on the thrusters significantly affect the efficiency of reorientation maneuvers, (ii) since thrusters are operational during reorientation maneuvers, a substantial amount of power is consumed to pump the bulk fluid, wasting the precious power storage of the vehicle, and (iii) the translational and attitude dynamics of model submarines and torpedo-like AUVs are highly coupled, and therefore, the vehicle cannot perform in-place attitude maneuvers.  Also, biomimetic swimmers with flapping wings or tails are not energy-efficient.   To address these problems, UC Berkeley resesarchers have developed a new swimmer with high maneuverability. The swimmer has no external fins, wings, or appendages for attitude control or stabilization, and does not generate excess flows while maneuvering. The swimmer has two counter-rotating propellers only for forward propulsion.  The novel AUV experiences the least form drag, and can make rapid in-place turns without turning off its propellers.
