Integrating Ultrasound Technology into a Fitness Tracking Device (1M, 2 B/S)
From iis-projects
Contents
Short Description
Ultrasound is a key technology in healthcare, and it is being explored for non-invasive, wearable, continuous monitoring of vital signs. However, its widespread adoption in this scenario is still hindered by the size, complexity, and power consumption of current devices. Moreover, such an application demands adaptability to human anatomy, which is hard to achieve with current transducer technology. In this work, we develop strategies and prototypes to advance ultrasound to a wrist-worn application, e.g. for monitoring vital signs.

Detailed Task Description
The main focus of this work is to build an ultrasound TX and RX circuit for a flexible polymer transducer technology and to propose design approaches for its integration into wrist worn applications. According to the level of the student and the chosen thesis type (BT/ST/MT) the work will include some or all following tasks:
Goals
Characterization
- VNA measurments of transducers
- Matching circuit design
Hardware Design
- Integration of existing TX and RX circuit prototypes for a flexible polymer transducer on a single evaluation board.
