Moving Towards 3D Bioprinted Cardiovascular Tissue

Cardiologists need to rely on the technology at their disposal. Shortages in available donor tissue for cardiac transplantation are driving the development of cardiovascular 3D bioprinting technologies.

Potential "One-Hour" COVID-19 Diagnostic Test Developed

Physician-scientists at the University of California, San Diego are the first to evaluate a new diagnostic testing system designed by Fluxergy, that holds promise for identifying the SARS-CoV-2 virus (also known as the novel coronavirus) in as little as 45 minutes and typically within one hour.

Wearable Device Camouflages its Wearer in all Weather

Researchers have developed a wearable technology that can hide its wearer from heat-detecting sensors such as night vision goggles, even when the ambient temperature changes--a feat that current state of the art technology cannot match.

Internet of Things: Lessons from EAS and RFID

Anti-theft tags (Electronic Article Surveillance) and Radio Frequency Identification RFID have much in common with the newer concept.

Ultrasound Device Improves Charge, Run Time in Lithium Batteries

Researchers have developed an ultrasound-emitting device that brings lithium metal batteries one step closer to commercial viability. Although the research team focused on lithium metal batteries, the device can be used in any battery, regardless of chemistry.

FreMon Scientific

FreMon Scientific - based in San Diego, USA - was demonstrating ZipThaw, its portable blood thawing device. The company aims to render the process of thawing blood in hospitals more efficient and to reduce waste.

Growing Strained Crystals Could Improve Performance of Perovskites

A new method could enable researchers to fabricate more efficient and longer lasting perovskite solar cells, LEDs and photodetectors. By growing thin perovskite films on substrates with different compositions, engineers have invented a way of fabricating perovskite single crystals with precisely deformed, or strained, structures.

New Chip Wakes Up Small Wireless Devices, Could Extend Battery Life

A new power saving chip developed by engineers could significantly reduce or eliminate the need to replace batteries in Internet of Things devices and wearables. The so-called wake-up receiver wakes up a device only when it needs to communicate and perform its function. It allows the device to stay dormant the rest of the time and reduce power use.

New soft actuators could make soft robots less bulky

Engineers have developed a way to build soft robots that are compact, portable and multifunctional. The advance was made possible by creating soft, tubular actuators whose movements are electrically controlled, which makes them easy to integrate with small electronic components.

Stretchable and flexible biofuel cell that runs on sweat

A unique new flexible and stretchable device, worn against the skin and capable of producing electrical energy by transforming the compounds present in sweat, was recently developed. This cell is already capable of continuously lighting an LED, opening new avenues for the development of wearable electronics powered by autonomous and environmentally friendly biodevices.

Shape-shifting robots built from 'smarticles'

Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as "smarticles" to unlock the principles of a potentially new locomotion technique.

Study identifies main culprit behind lithium metal battery failure

A research team has discovered the root cause of why lithium metal batteries fail—bits of lithium metal deposits break off from the surface of the anode during discharging and are trapped as "dead" or inactive lithium that the battery can no longer access.

Robotic contact lens controlled by the eyes

A research team has developed a soft robotic lens whose movements are controlled by the eyes—blink twice and the lens zooms in and out; look left, right, up or down and the lens will follow.

3D printed get up and go bots getting closer, study says

Robotics researchers have for the first time used a commercial 3D printer to embed complex sensors inside robotic limbs and grippers. But they found that materials commercially available for 3D printing still need to be improved before the robots can be fully functional.

New mechanism allows lower energy requirement for OLED displays

Scientists have found a way to significantly reduce the amount of energy required by organic light emitting diodes (OLEDs). OLEDs have attracted attention as potential replacements for liquid crystal diodes, since they offer advantages such as being flexible, thin, and not requiring backlighting.

Technique unlocks graphene for semiconductors

To truly be useful, graphene would need to carry an electric current that switches on and off, as silicon does in the form of billions of transistors on a computer chip.

Cooling and heating patch serves as personal thermostat

Engineers have developed a wearable patch that could provide personalized cooling and heating at home, work, or on the go.

Robots to the rhino rescue

With just two northern white rhinos remaining in the world, both of whom are female, scientists are racing against the clock to rescue the species from the brink of extinction. Decades of poaching and habitat loss have led to their dramatic decline. Hope for their survival now rests on scientists' ability to develop innovative methods for repopulating the species.

Printed sensors provide on the spot fentanyl detection

Researchers have developed screen-printed sensors that could offer a faster, convenient and low-cost method to detect the drug fentanyl. The sensors can detect micromolar concentrations of fentanyl in just one minute. They are easy to produce, cost only a few cents apiece, and are disposable.

Robots to assist dementia caregivers

Building robots that can help people with dementia has been a longtime goal for roboticists. Yet until now, no one has sought to survey informal caregivers, such as family members, about what characteristics and roles these robots should have.
