These Screen-printed, Flexible Sensors Allow Earbuds to Record Brain Activity and Exercise Levels

Earbuds can be turned into a tool to record the electrical activity of the brain and levels of lactate in the body with two flexible sensors screen-printed onto a flexible surface.

Wearable Electronics for Continuous Cardiac, Respiratory Monitoring

A small and inexpensive sensor, announced in Applied Physics Letters and based on an electrochemical system, could potentially be worn continuously by cardiac patients or others who require constant monitoring. A solution containing electrolyte substances is placed into a small circular cavity that is capped with a thin flexible diaphragm, allowing detection of subtle movements when placed on a patient’s chest. The authors suggest their sensor could be used for diagnosis of respiratory diseases.

Smartphone Use Offers Tool to Treat MS, Other Diseases

Monitoring how patients with multiple sclerosis or other degenerative diseases use their smartphones could provide valuable information to help get them better treatment. In the journal Chaos, researchers used an app to record the keystroke dynamics of a control group and those of subjects in various stages of MS treatment. In doing so, they observed changes in the way people with MS typed that were not seen in subjects who did not have the disease.
