Dr Chan Ping Yi
Dr. Chan Ping Yi has six years of experience in biomechanics, particularly in developing tremor measurement system for Parkinson’s disease tremor. It involves the kinematics of human motion, specifically in multi-degrees-of-freedom relative motions. This research requires the translation of mathematical equation to working algorithm to quantify motions using inertial sensor readings.
The quality of the research work is proven by the success in publishing papers in IEEE Transactions on Neural Systems and Rehabilitation Engineering as well as Scientific Reports by the renowned published, Springer Nature. The system and methods of quantifying tremors of multiple-degrees-of-freedom coupled motions have been filed for patent in Malaysia (MyIPO) and Patent Cooperation Treaty (PCT). The work also led her and the research team to win RM 20,000 in an innovation competition organized by Universiti Teknologi PETRONAS.
She has more than a year of working experience as a postdoctoral fellow in Universiti Sains Malaysia. During the service, she is actively involved in a few industry-related research projects.
Her research interest is to further expand the measurement system to cater for advanced tele-monitoring of tremor and other symptoms of movement disorders. Other research directions include developing of tremor compensation system for the Parkinson’s disease patients and electromagnetic energy harvester. The research outcomes are anticipated to create greater impact to the society and environment.

Dr Chan Ping Yi's research interests include developing:
- Advanced tele-monitoring system of tremor and other symptoms of movement disorders
- Tremor compensation system for patients with severe tremor
- Renewable energy, particularly on electromagnetic energy harvesting
A tremor measurement system was developed for quantifying hand-arm tremor. It was tested in the laboratory using own developed tremor simulator and in clinics on 70 Parkinson’s disease (PD) patients and 62 normal subjects to prove its reliability for practical use and the significance of using proposed system in characterizing pathological and physiological tremors.
The project output is beyond research papers. The productization and commercialization of the system are in the pipeline. Her current research centers around motion-related measurement and control system. With the experience of bringing a research to near end-user product, she also aspires to work on another project that impact greater to the society and environment, by expanding the envelope of her research capability in energy harvesting of electromagnetic wave.
Title: Advanced tele-monitoring system of tremor and other symptoms of movement disorders
She is working on improving the tremor measurement system for long-term and automated detection. The challenge is to differentiate the symptom with undesired movement in an uncontrolled environment. The system is expected to be used at patients’ home and the data are able to be accessed remotely. She is also interested in capturing other motor symptoms of movement disorders.
Title: Tremor compensation system for Parkinson’s disease patients
This project focuses on providing a solution to counteract the severe tremor suffered by the patients. By using miniature actuators, inertial sensor, and a control system with artificial intelligent predicted of the correct signals (separate tremor from intended movement) to compensate the uncontrollable tremor. Soft robot and servomotors are the actuation solution to be researched on for providing tremor compensation.
Title: Electromagnetic energy harvesting
The aim of this project is to develop a system that harvests electromagnetic energy throughout the day, by taking into account the weather and the absence of sunlight. Photovoltaic system is taken as the core technology and it is required to further expand the frequency range of electromagnetic wave convertible to electricity, i.e. through improving the response and efficiency of the harvester in system level spectrum. The challenge is to expand the spectral quantum efficiency beyond visible light region to harvest the maximum possible electromagnetic energy from the ambient at different hours. By using power management unit, energy storage and microcontroller, the excess energy is stored during high energy supply and released for later use.
