More and more wearable devices enable real-time tracking and monitoring of our health and physical indicators. Rigid electronic components are used on many wearable devices, which in some respects have certain limitations, such as monitoring of body movements. Scientists have developed scalable electronic components that will have broad application potential in the field of wearable health products.
Dr. John Rogers is a professor of neurosurgery at the McCormick School of Engineering. He developed the sensing device in collaboration with Shirley Ryan AbilityLab. As an advanced medical device, this retractable electronic device can be worn outside the hospital, even in extreme sports.
Dr. John Rogers is the designer of this wearable stroke rehabilitation device.
Rogers presented the impact of scalable electronics on stroke rehabilitation at the annual meeting of the American Association for the Advancement of Science (AAAS) in Austin, Texas. The sensors developed by Rogers can be applied directly to the skin surface and can be deformed well with the movement of the body, while providing detailed monitoring of health indicators including heart function, muscle activity and sleep quality.
For stroke patients, traditional rehabilitation training and tracking often takes place in the hospital. Strokes can affect many of their body's motor function, and monitoring of each sport and corresponding rehabilitation guidance tends to be untrackable as they leave the hospital. Therefore, it is possible to closely track the body's indicators in any environment, and it has a good tracking and guiding effect for the rehabilitation of stroke patients.
This electronic device can be used for monitoring a variety of physical conditions.
"Retractable electronic components allow us to observe the situation in the patient's body at levels not possible with traditional wearable devices," Rogers said. "The key is to make them as close as possible to the body." For many rigid electronic devices This is obviously hard to do.
The stretchable sensing device developed by Rogers looks like a “band-aidâ€. Its precision sensing has a level that is difficult to achieve with conventional sensors. When this "band-aid" is attached to the patient's throat, it measures the patient's ability to swallow and language. This means that the sensor can help doctors and patients to achieve the diagnosis and treatment tracking of "aphasia" caused by stroke.
In traditional diagnosis and treatment, language pathologists check the patient's language ability through a device such as a microphone, but environmental sounds from the outside may interfere with the results of the examination. This new stretch sensor is different. Rogers explained, “Our sensor solves this problem because it measures the vibration of the vocal cords to monitor the patient's vocalization. “But they are only effective when they are wearing the throat. They are very sensitive to the skin in the area. The new materials we developed for this sensor can stretch with the movement of the body, and the discomfort for the patient is Very low."
Given the sensitivity and comfort of this sensor, it is expected to be used for monitoring and evaluation in a variety of situations. Moreover, the sensor's intermodal system can wirelessly transmit data to the clinician's cell phone and computer, providing patients with quantitative, whole-body images of real-time physical and physiological responses. Because the sensors are wireless, they eliminate the barriers to traditional health monitoring devices in clinical settings. Patients can also wear them after they leave the hospital so that the doctor can understand how the patient is in life. This will be of great help to the observation and treatment of patients with stroke.
