The Simon Fraser University Technology Licensing Office has Adventus work on a market assessment study supported through the NSERC Idea to Innovation grant program, for a technology entitled "Leech-mimic 3D printed origami (LMO) sensor composed of the non-auxetic tip with auxetic bodies to monitor electrophysiological signals" developed by Dr. Woo Soo Kim, Professor in the School of Mechatronic Systems Engineering at SFU. Monitoring of blood pressure (BP) plays a crucial role in medical diagnosis because high BP is deeply related to several chronic diseases. The increasing prevalence of cardiovascular diseases and the growing aging population are leading to rising demand for personal healthcare systems that collect the BP of patients during their daily life. Therefore, accurate and/or frequent BP monitoring without clinical settings (such as mobile or wearable devices for remote or general healthcare monitoring) is anticipated to drive the global ECG sensor market. In fact, both ECG and PPG (photoplethysmography) technologies are becoming easily available, low-cost, and convenient with portable devices. The pulse arrival time (PAT) parameter, indicating the time taken from the pulse waveforms to traverse from the heart to a distal site, is often used with the paired ECG-PPG sensing system monitoring the BP continuously. The BP monitoring with PAT requires reliable ECG signals near the heart and PPG signals on the distal site. Thus, stable positioning of dry ECG electrodes on the skin is essential to obtain effective ECG signals. SFU researchers have developed a leech-mimic 3D printed origami (LMO) sensor composed of the non-auxetic tip with auxetic bodies to monitor electrophysiological signals. The leech-mimic structure (LMO) provides stable contacts and applies reliable but slight suction to the human skin so that the LMO is still attached to the human skin when the patient is in motion. This dry electrode for cardiovascular monitoring systems makes monitoring time faster and much more comfortable compared to the current wet gel-type electrodes used in monitoring ECG and BP.
