Tremor Watch

Hélène Meunier - CRI

I have been working on the "tremor watch" project which aims at using low cost wearable device for logging and quantifying pathology induced tremors (e.g parkinson disease). I began my internship by a state of the art gathering information about the wearables dedicated to monitor and even counterbalance tremors. The aim was to better understand what was already existing and what were the needs and the challenges for tomorrow. I worked on several scientific articles to better understand Parkinson tremors and other diseases involving tremors. The first challenge was to implement a real time data graph to visualize the accelerometery, angular position and magnetometry using Arduino and python. Then I programmed the associated transfer functions. Currently, my device is being tested on a Parkinson patient so that I can get data. Next step is adapting my device by filtering frequencies (noise reduction…) The intention of the filters is to find for each patient the exact pathology causing these tremors. There is still work that needs to be done after that, on counterbalancing tremors using haptic feedback.

Low-cost and Portable Peritoneal Dialysis Machine

Chetan Velumurugan - CRI

Chronic Kidney Disease (CKD) is an important public health challenge given its high prevalence, morbidity and mortality. The true burden of CKD in low and middle-income countries is not known due to the absence of national registries. South Asia suffers from a large and increasing burden of untreated end stage kidney disease (ESKD). India, one of the largest and most populous countries in South Asia has 1 million patients who require dialysis on a regular basis, out of which only around 10 percent can actually afford or access it. Large numbers of patients below the poverty line, low gross domestic product, and low monetary allocations for health care have limited the availability of renal replacement therapies (RRT) to large sections of the population. Most patients with ESKD in India die without receiving appropriate treatment due to the high costs of treatment. Hence, the cost of treatment becomes a deciding factor between the two modalities of dialysis, which are Hemodialysis (HD) and Peritoneal Dialysis (PD). Both HD and PD are shown to have comparable patient survival rates. Dialysis prescriptions are not optimized for patients and HD is the most common modality followed by transplantation, and PD stands a distant third in RRTs. Also, a majority of nephrology-related services are concentrated in expensive private sector hospitals in urban locations. This makes PD an attractive option for a majority of rural patients. Low-cost Peritoneal Dialysis Machines will play an important role in providing accessible and affordable dialysis treatments for people in low resource settings across India. Towards this goal, my research focuses on the design and development of a Low-cost and Portable Peritoneal Dialysis Machine.
