View source for Skin coupling media characterization for fitnesstracker applications (1 B/S)

[[File:fitness_tracker_coupling.png|thumb|490px]]



==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 into a wrist-worn application, e.g. for monitoring vital signs.

==Detailed Task Description==
The focus of this work is to support the development of an ultrasound technology and its adaptation to a wrist-worn application. Depending on the level of the student and the type of work chosen (B/S/M), the work will include some or all of the following tasks: 

===Goals===

=====Literature Research=====
* Research of commercially available coupling media
* Evaluation of coupling media in terms of: acoustic properties (e.g., attenuation), 3d design and integration, farbication complexity, cost. 

=====Testbench Design=====
* Design of a coupling media testbench
* Design of casts and fabrication of prototypes
* Development of software for testing
* Prototype integration into a wrist band

=====Testing=====
* Ultrasound characterization of coupling media

===Practical Details===
