Smart Aging We aim to develop wearable and ambient sensing device technologies and personalized AI/ML algorithms for continuous, longitudinal assessment of older adults' health conditions during their daily living activities (ADL). Such longitudinal health dataset will enable early detection and personalized management of chronic and neurodegenerative diseases.

Comparing with conventional wide-field imaging microscopes, confocal microscopy hold significant advantages in image contrast enhancement, 3D sectioning capabilities, and compatibility with specialized detectors. For applications such as live cell imaging, slow acquisition speed is a key barrier to adaption of confocal microscopy. While wide-field microscopy is typically faster, multiplexed confocal schemes such as using a spinning foci array can significantly increase the image acquisition rate…

The motivation behind imaging and tracking an endoscope during a procedure in the gastrointestinal tract is related to a) the path of the endoscope internally and b) small object tracking for early detection of diseases. In colonoscopy, it is important to monitor the progression or recurrence of suspected cancerous lesions (e.g., polyps). However, because the colon is contractile and mobile, it is very difficult to relocate a lesion (e.g., a polyp) during follow-up and even during the same pr…

Revised: 2020 06 24 Background and Challenges As our population continues to age we are becoming more aware of challenges faced by our elders and increases in costs to the healthcare system. The quality of life of our elders tends to decline with age as they face new challenges. In many cases elderly residents must move to a new home or retirement community in order to receive the assistance they need as they age. Several remote monitoring technologies are emerging with a focus on improving t…

Microstructure materials are currently used in different fields. One of these areas is sensor devices such as microfluidic devices. The devices are made from transparent materials such as glass and PDMS (Polydimethylsiloxane). There are several techniques that are currently used to remove substance and create microchannels on material surface, laser ablation is one of the important methods that can be used in microfabrication. This importance results from the development of laser. In the past, l…

Conventional optical spectroscopy and imaging systems are large, complex and costly optoelectronic instruments comprised of lasers, spectrophotometers, and detectors. Often, their size is the limiting factor for their use in certain applications such as in-situ monitoring of physiological processes and distributed environmental sensing. In practice, there are strong demands for miniaturized, integrated devices for biomedical applications.

Revised: 2019 05 06 Background and Challenges There are several fluid monitoring challenges in a wide range of applications from wastewater treatment plant process monitoring, environmental water quality monitoring, and biofluid analysis. Optofluidic devices share several of the advantages of microfluidic devices and optical detection methods. Microfluidic channels are used to deliver small volumes of samples to the sensitive region of the device. Currently there are limitations in fluid analy…

The infrastructure is based on a retrofitted residential house to develop and test smart technology for long term health monitoring of older adults living in their own homes. The motivation behind developing a smart home for health monitoring is centered around two key aspects: (i) cost of care and (ii) quality of care. The public expenditure on health care in Ontario alone surpassed $50 billion in 2014. Our proposed strategy to reduce the growing financial and social pressure is to create a h…

Smart Diet and Nutrition Monitoring Project Description DiTrack is a smartphone-based dietary monitoring app designed to make nutrition tracking easier, especially for older adults recovering from hospitalization or living in long-term care. Traditional methods like food diaries or recall surveys are often unreliable and difficult for older adults to use. DiTrack solves this by allowing users to log meals with emphasis on simple photo capture and voice annotations. This results in a reduced n…
