Biography
Dr Louis Phee is a Professor at Nanyang Technological University (NTU), Singapore. He is the Chair of the School of Mechanical & Aerospace Engineering at NTU. He graduated from NTU with the B.Eng (Hons) and M.Eng degrees in 1996 and 1999 respectively. He obtained his PhD from Scuola Superiore Sant’Anna, Pisa, Italy in 2002 on a European Union scholarship. His research interests include Medical Robotics and Mechatronics in Medicine. Currently, Dr Phee is the Principal Investigator of a few interdisciplinary projects. He had served as the Program Manager of A*STAR’s inaugural MedTech Program. Currently, he is also the CEO of EndoMaster Pte Ltd, a company he co-founded to commercialize a surgical robotic system he developed. Dr Phee was awarded the Young Scientist Award (2006), the Outstanding Young Persons of Singapore Award (2007), the Nanyang Outstanding Young Alumni Award (2011), Nanyang Innovation and Entrepreneurship Award (2013) and the President’s Technology Award (2012). In 2005, he was awarded the Best Paper Award at the prestigious IEEE International Conference on Robotics and Automation. He has published over 50 international journals, book chapters and a few licensed intellectual properties.

    Magnetically Actuated Ingestible Weight Management Capsule
    The research objective of this proposal is to implement an electromagnetic actuation mechanism into a mechatronics capsule as an ingestible weight-loss device to solve obesity.
    In the long run, we envision having an over-the-counter mechatronics weight loss capsule for obese and moderately obese people. Upon ingestion, the capsule will promote weight loss by expanding and occupying the gastric space, hence introducing the feeling of satiety. This mechatronics capsule will promote weight loss in a safe and a non-invasive manner.
    Our capsule offers a safer and less invasive method for losing weight as compared to other weight-loss methods. Oral administration reduces hospitalization and recovery time, eliminates complications related to endoscopy or surgery, and mitigates long-term side effects from drugs. In addition, our capsule provides a more effective weight-loss due to its dynamic administration process. Furthermore, it can be sold at a much lower price as compared to the other treatment alternatives.

    Development and Evaluation of Novel Mechatronic Tracheostomy Tube for Automated Tracheal Suctioning
    Mechanical ventilation is required to aid patients with breathing difficulty to breathe more comfortably. A tracheostomy tube is inserted through an opening in the neck into the trachea, below the vocal cords. This opening is either created surgically or using a percutaneous dilatational technique. The tube sits in the trachea, above the carina, and before the airways branch into the left and right main bronchi. In mechanical ventilation, the tube is connected to a ventilator and air is moved in and out of the lungs via positive pressure. In this process, mucus will accumulate at the point of branching into the bronchi. Currently this mucus is manually removed every half an hour by inserting a suction tube via the tracheostomy to reach the point of branching. Nurses spend millions of person-hours yearly performing this task. This procedure could be automated to save significant person-hours. An automated system also allows the patient to recover at home, rather than stay in hospital solely for nurses to remove mucus periodically. We propose to develop a mechatronic device to perform automatic tracheal suctioning in conjunction with a tracheostomy tube.
