Sticky Sensors for Internal Organs

Sensors can go almost anywhere and do almost anything – and soon, sensors may be making their way to your internal organs.

Researchers have developed an electronic sensor, of which they will attach to a newly designed sticky sheet in order to attach to the body’s organs.

This from Popular Science:

A team of researchers based at several Japanese universities made prototype sticky sensors that they’ve now tested on the still-beating hearts of living rats. The sensors measured strain and electrical activity, both of which are created when a heart beats. In a test, the sensors maintained good contact with the rats’ heart for three hours.

Students at the University of Wisconsin-Madison are not just interested in improving technology and creating innovative design, but rather they are determined to make us rethink the way the physical and digital world interact.

These students have spent months in the University’s Internet of Things Lab, where they work to measure, monitor and control the physical world by heightening its interaction with the Internet.

The main innovation that the lab has developed is a football helmet that can detect injuries.

Cross-disciplinary teams of students have come together to develop a high-tech football helmet that has brain wave probes and a device that measures acceleration forces, which gives the ability to detect concussions on the field and directly communicate the information to medical staff.


Helping Medicine with Graphene Quantum Dots

Researchers from the University of Sydney have recently published their findings that quantum dots made of graphene can improve bio-imaging and LEDs.

The study was published in the journal Nanoscale, where the scientists detailed how activating graphene quantum dots produced a dot that would shine nearly five times bright than the conventional equivalent.

Essentially, the dots are nano-sized semiconductors, which are fluorescent due to their surface properties. However, this study introduces the utilization of graphene in the quantum dot, which produces an extra-bright dot that has the potential to help medicine.


Clothes That Monitor, Transmit Biomedical Info

We’ve hear about smartphones and “smart cars,” and even such recent developments as the smart highway – but what about a smart textile?

Researchers from Université Laval’s Faculty of Science and Engineering and Centre for Optics, Photonics and Lasers are well on their way to developing clothes that can monitor and transmit biomedical information on wearers.

By using sensor technology and wireless networks, this smart textile will be able to track and transmit this medical information – which has the potential to be extremely beneficial for people suffering from chronic disease, firemen and police offers, and people who are elderly.
