Wearable Sensor Monitors Electrolytes in Real-Time

Wearable Sensor Monitors Electrolytes in Real-Time
Jun-08-14
Both soldiers and athletes could benefit from a new wrist-worn device that continuously monitors electrolyte levels, warning the user before they become overly-dehydrated.

The prototype sensor device is equipped with nine microneedles that extract the fluid from between the skin cells just beneath the wearer's wrist, and then pass the extracted potassium to a cartridge able to measure the electrolyte levels in real-time. The device is painless, and can be tailored to selectively measure specific electrolytes, such as sodium or calcium.

The team is also looking toward the future, with possible plans for a "sense-respond" device able to actually add electrolytes to the user's body as needed, before they get dangerously low.
