Engineers Create Artificial SkinThat "Feels" Temperature Changes
A team of engineers and scientists at Caltech and ETH Zurich have developed an artificial skin capable of detecting temperature changes using a mechanism similar to the one used by the organ that allows pit vipers to sense their prey.The material could be grafted onto prosthetic limbs to restore temperature sensing in amputees. It could also be applied to first-aid bandages to alert health professionals of a temperature increase --a sign of infection--in wounds.
Researchers Develop Wearable, Low-Cost Sensor to Measure Skin Hydration
Researchers from North Carolina State University have developed a wearable, wireless sensor that can monitor a person's skin hydration for use in applications that need to detect dehydration before it poses a health problem.The device is lightweight, flexible and stretchable and has already been incorporated into prototype devices that can be worn on the wrist or as a chest patch.The sensor consists of two electrodes made of an elastic polymer composite that contains conductive silver nanowires.
Wearable "Watches" to MonitorYour Blood Pressure
The NIST-Tufts blood pressure phantom consists of a slab of squishy silicone, which stands in for human tissue, sitting on top of a metal plate, the stand-in for bone. A pliable tube runs through the silicone to mimic an artery, through which fluid flows via a mechanical heart pump.The materials were carefully selected to match the properties of skin, soft tissues, bone, and artery walls, the researchers say. But unlike actual live human tissue, the phantom can easily have sensors running through it, measuring the pressure changes that occur each time water is pumped through the tube.
UTA Materials Scientist Invents Breath Monitor to Detect Flu
The hands are controlled with shoulder shrugs and a shoulder harness. Strong shoulder shrugs result in tighter hand grips.The design is a cross between a cosmetic hand and a functional split hook.The user can hold a cellphone or carry a bag. However, it does not provide the strength of a fully functioning hand.
Paragon 28 Announces Bone Fixation System for Foot and Ankle
The Baby Gorilla Mini Plating System leverages the modularity, optionality, and specificity in the classic Gorilla Plating system and offers a set of implants for procedures that may require narrower plates and smaller screws matching the size and anatomy of small bones within the foot and ankle.The system provides 65 unique Baby Gorilla-plating options from 13 plating families. All plates are designed to accept both 2.0 mm and 2.5 mm locking and non-locking variable angle plate screws.
FireflySci Turns Up the Voltage with New Electroporation Cuvettes
FireflySci's model of electroporation cuvettes calledType 704P are strictly manufactured to efficiently transfer DNA and RNA into a wide variety of cells. It is imperative that there is a uniformity in the way not only the polycarbonate is manufactured but mainly the aluminum electrode plates. If these are not produced with high parallelism and uniformity there is the possibility of arcing electricity, which can damage or destroy samples.This high standard of quality ensures that results are consistent and reproducible.
