Wearable to Continuously Monitor Glucose, Alcohol and Lactate
Imagine being able to measure your blood sugar levels, know if you've had too much to drink, and track your muscle fatigue during a workout, all in one small device worn on your skin. Engineers have developed a prototype of such a wearable that can continuously monitor several health stats—glucose, alcohol, and lactate levels—simultaneously in real-time.

New Brain-Computer Interface With a Flexible Backing
Engineering researchers have invented an advanced brain-computer interface with a flexible and moldable backing and penetrating microneedles. Adding a flexible backing to this kind of brain-computer interface allows the device to more evenly conform to the brain's complex curved surface and to more uniformly distribute the microneedles that pierce the cortex. The microneedles, which are 10 times thinner than the human hair, protrude from the flexible backing, penetrate the surface of the brain tissue without piercing surface venules, and record signals from nearby nerve cells evenly across a wide area of the cortex.

New Method to Make AI Generated Voices More Expressive
Researchers have found a way to make AI-generated voices, such as digital personal assistants, more expressive, with a minimum amount of training. The method, which translates text to speech, can also be applied to voices that were never part of the system's training set.

CRISPR-based Rapid Diagnostic Tool for SARS-CoV-2
Blending experts from molecular genetics, chemistry and health sciences, researchers have created a rapid diagnostic technology that detects SARS-CoV-2, the coronavirus that causes COVID-19. The new SENSR (sensitive enzymatic nucleic acid sequence reporter) is based on CRISPR gene-editing technology that allows speedy detection of pathogens by identifying genetic sequences in their DNA or RNA.

Making Space Travel Inclusive for All
In a weightless, microgravity environment like space, what do ability and disability look like? How can someone with partial sight or impaired mobility navigate in a confined space like the space station? As scientists and innovators continue to push the boundaries of spaceflight and the possibility of human life on other planets, how can we build space infrastructure that is inclusive of all humans?

New Solid-state Battery Surprises
Engineers created a new type of battery that weaves two promising battery sub-fields into a single battery. The battery uses both a solid state electrolyte and an all-silicon anode, making it a silicon all-solid-state battery. The initial rounds of tests show that the new battery is safe, long lasting, and energy dense. It holds promise for a wide range of applications from grid storage to electric vehicles.

Super Productive 3D Bioprinter Could Help Speed up Drug Development
A 3D printer that rapidly produces large batches of custom biological tissues could help make drug development faster and less costly. Nanoengineers developed the high-throughput bioprinting technology, which 3D prints with record speed--it can produce a 96-well array of living human tissue samples within 30 minutes. Having the ability to rapidly produce such samples could accelerate high-throughput preclinical drug screening and disease modeling.

Robotic Seafloor Survey Completed
An expedition led by UC San Diego's Scripps Institution of Oceanography mapped more than 36,000 acres of seafloor between Santa Catalina Island and the Los Angeles coast in a region previously found to contain high levels of the toxic chemical DDT in sediments and the ecosystem. The survey identified an excess of 27,000 targets with high confidence to be classified as a barrel, and an excess of 100,000 total debris objects on the seafloor.

Sewage-Handling Robots Help Predict COVID-19 Outbreaks
In earlier days of the COVID-19 pandemic, before diagnostic testing was widely available, it was difficult for public health officials to keep track of the infection's spread, or predict where outbreaks were likely to occur. Attempts to get ahead of the virus are still complicated by the fact that people can be infected and spread the virus even without experiencing any symptoms themselves.

Wearable Microgrid Uses the Human Body to Power Small Gadgets
Nanoengineers have developed a "wearable microgrid" that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing.

Weakness is Strength for this Low-Temperature Battery
Nanoengineers have discovered new fundamental insights for developing lithium metal batteries that perform well at ultra-low temperatures; mainly, that the weaker the electrolyte holds on to lithium ions, the better. By using such a weakly binding electrolyte, the researchers developed a lithium metal battery that can be repeatedly recharged at temperatures as low as -60 degrees Celsius—a first in the field.
