About the Group

It is universally accepted that current health care systems around the world need improvement. The Platforms for Ultra-Low-Power Biomedical Electronics team is inspired by this problem to make electronics used in health care and other physiological environments more user-friendly and accessible. This is accomplished by the integration of energy efficient circuits in small, easy-to-use platforms that can operate over long periods of time on a single battery charge.

Remote medical monitoring, also termed telemedicine, or connected health, is an example of a biomedical system requiring integration of sophisticated electronics and devices to make the resulting platform viable to the end user. The system starts by collecting various physiological signals, such as a patient's heart rate, EKG, blood pressure, oxygen saturation, or EEG. These signals are then locally processed and compressed, then transmitted to a local relay. The relay then wirelessly transmits the information securely over the internet to the patient's physician or a remote monitoring facility.

The design of such a platform requires expertise in a wide range of fields:

• Physical sensors & humans interfaces
• Instrumentation/analog front ends
• Analog-to-digital convertors
• Microcontrollers & DSPs
• RF front ends & digital basebands/modems
• Networking algorithms & secure communication

All of these individual components must not only be optimized for minimum energy consumption, they must also be optimized together to form a system that is both compact and energy efficient.
