The first wireless dust sized sensor that can be implanted in the body has been built by engineers at UC Berkeley. The work brings closer the day when a Fitbit-like device could monitor internal nerves, muscles, or organs in real time. Because these battery-less sensors could also be used to stimulate nerves and muscles, the… Read more

A new flexible sensor system can measure metabolites and electrolytes in sweat, calibrate the data based upon skin temperature and sync the results in real time to a smartphone. While health monitors have exploded onto the consumer electronics scene over the past decade, researchers at the University of California, Berkeley say this device is the… Read more

Estrogen is a tiny molecule, but it can have big effects on humans and other animals. Estrogen is one of the main hormones that regulates the female reproductive system – it can be monitored to track human fertility and is sometimes administered to livestock like cows and sheep to control the reproductive cycle. Researchers from… Read more

Engineers have figured out how to mass produce an inexpensive wearable patch that continuously monitors vital signs for health and performance tracking. They believe the tattoo-like device has the potential to outperform more traditional tools like cardiac monitors. The breakthrough is a repeatable “cut-and-paste” method that cuts manufacturing time from several days to only 20… Read more

Optical sensors may be uniquely suited for use in robotic hands, according to researchers who have developed a three-fingered soft robotic hand with multiple embedded fiber optic sensors. They have also created a new type of stretchable optical sensor. By using fiber optics, the researchers were able to embed 14 strain sensors into each of… Read more
