Ultra low power microelectronics for wearable and medical devices

The requirements for wearables and portable medical devices present a number of challenges in terms of integration, autonomy and connectivity, and demand a careful co-design of hardware and software to reach optimum performance. This paper addresses these challenges by way of some recent examples of ASICs designed for ECG, EIT (Electrical Impedance Tomography) and PPG (Photoplethysmography) sensors as well as for non-invasive blood pressure monitoring.
