Kim, Tae-Ho Kim, a PhD student and a team in SFU’s Additive Manufacturing Laboratory, have replaced the traditional blood pressure measurement process by recreating the folding mechanism of the leech in the sensor design. their 3D printable origami.
“Our origami-inspired dry electrode has unique features such as suction to grip and the ability to fold,” said Kim, professor and associate director of SFU’s School of Mechatronic Systems Engineering. is inspired by nature. “In keeping with nature, we found that in addition to the complex mechanisms of the leech’s adhesion characteristics, these organisms have suckers and an extendable rear body, while its organs are appropriately expands and contracts to maintain better adhesion to the victim. Taking this together, we found that origami can achieve similar movements and can also be customized.”
How Robots Work
The fingertips of the robot should be placed on the patient’s chest. The LIO sensors are integrated with the blood pressure monitor and it is estimated by the combination of data from the electrocardiogram (ECG) and photocardiogram (PPG) results using the sensors on the fingers. of each hand of the robot.
Paired sensors can generate a patient’s systolic and diastolic blood pressure using predefined algorithms. This method is much more effective than the traditional method of using a cuff-based digital sphygmomanometer.
Kim’s previous work included programming sensitive robots to measure other human physiological signals, such as electrocardiograms (which monitor heart rate), temperature, and breathing rate.
“Robotics offers a promising method to reduce risk and improve the quality and efficiency of patient care as centralized telehealth technology,” says Kim. The researchers are planning to further test their new process and develop next-generation sensors, which they hope will lead to biologically meaningful implementations.
“Blood pressure monitoring is an essential medical diagnostic tool for many chronic diseases and overall good health. The use of sensor robots in medical healthcare systems has significant advantages. because they can assist healthcare workers in monitoring a patient’s vital signs while also creating a welcoming environment for these patients who may need to be isolated.”
Kim hopes that robots can provide a future platform or bridge between healthcare workers and telemedicine patients with “the potential to play an essential role in the new era of telehealth. ”
The research was supported in part by the Discovery and Acceleration Supplemental Grant, funded by the Natural Sciences and Research Council of Canada (NSERC).
