Physical fitness tracker bracelets and watches offer valuable facts, this kind of as move rely and heart level, but they normally just can’t offer additional detailed info about the wearer’s health.
Now, scientists reporting in ACS Utilized Supplies & Interfaces have formulated sensible digital glasses (e-glasses) that not only keep an eye on a person’s mind waves and entire body movements but also can perform as sun shades and let people to management a video recreation with eye motions.
Gadgets that measure electrical indicators from the mind (electroencephalogram EEG) or eyes (electrooculogram EOG) can assist diagnose circumstances like epilepsy and rest ailments, as perfectly as management computer systems in human-device interfaces. But acquiring these measurements needs a continuous physical call in between pores and skin and sensor, which is difficult with rigid devices.
Suk-Gained Hwang and colleagues wanted to combine comfortable, conductive electrodes into e-glasses that could wirelessly keep an eye on EEG and EOG indicators, ultraviolet (UV) depth, and entire body movements or postures, although also acting as a human-device interface.
The scientists created the glasses’ body with a 3D printer and then extra adaptable electrodes near the ears (EEG sensor) and eyes (EOG sensor). They also extra a wireless circuit for motion/UV sensing on the side of the glasses and a UV-responsive, color-adjustable gel inside of the lenses.
When the sensor detected UV rays of a specified depth, the lenses altered color and grew to become sun shades. The motion detector permitted the scientists to monitor the posture and gait of the wearer, as perfectly as detect when they fell. The EEG recorded alpha rhythms of the mind, which could be applied to keep an eye on health.
At last, the EOG keep an eye on permitted the wearer to conveniently shift bricks close to in a popular video recreation by changing the way and angle of their eyes. The e-glasses could be valuable for electronic health care or digital reality apps, the scientists say.
