Human Gait Analysis and Low-Cost Devices for Gait

Human Gait Analysis and Low-Cost Devices for Gait

We develop and use low-cost accelerometers to record gait related movement signals during walkingand use the same to classify and differentiating the gait phases.  Also, EEG and accelerometer sensors are being employed to understand the coordination between the central nervous system, the limb, and the musculoskeletal system that helps to develop EEG brain computer interfaces for assistance during walking.

A low-cost, low-power wearable ECG-monitoring monitoring framework that utilizes wireless body sensors, mobile phones, and web browsers for monitoring cardiac patients who are in remote areas. The device can be worn either as a necklace or as a belt and continuously monitors and analyzes a patient’s ECG. The ECG data is sent over wireless networks, in real-time, to the patient’s cardiologist/doctor, with alerts if a patient requires examination. The prototype version of the Amrita Spandanam was unveiled by the current Prime Minister of India, Shri Narendra Modi on September 27th, 2013. Revolutionizing remote cardiac care, our wearable low-cost, low-power ECG device utilizes wireless sensors, smartphones, AI, and the web. Continuously analyzing ECG data, it transmits real-time information, triggering instant alerts for crucial exams, ensuring no cardiac patient falls through the cracks.

Project goals

  • Development of a prototype 3-lead (6/2 channel) small form factor wearable device for continuous remote ECG monitoring.
  • Context aware algorithms for processing and analysis of continuous ECG for activity detection.
  • Decision support system for real-time warning of heart abnormalities.
  • Seamless heterogeneous connectivity (GSM / 2G / 3G / WiFi) and integration with an existing HIS.
  • Deployment of Amrita Spandanam device in villages
