MRES.B.02.02 Multifunctional materials and Wearable Devices
This course module focuses on a multidisciplinary field of the electronic devices and the clothing items used for the operation of the sensors, the actuators and the communication devices for the acquisition of biological signals, process and transmission of the respective information, the operation of actuators etc. The textile based electrical energy harvesting is also an important function of the wearable systems.
Among the multifunctional materials, the most interesting ones are those which can be found or transformed in fibrous form, permitting their integration in the textile materials of the clothing items. Consequently, the course module covers both fields and enables the analysis and the design of wearable electronic systems based on textile substrates on the human body.
The contents of the module are outlined as follows:
- Principles of wearable technology
1.1 Wearable devices
1.2 Wearable signal interfaces
