Smartphone based user interface for wearable electronic systems

 

Problem Definition:

Wearable electronic systems are getting more and more attention as they create an added value for textile based products. These systems allow to integrate intelligence in clothes (sensors) or increase the interaction between the user and his environment (lighting for safety).
Wearable electronic systems integrated in textiles are mainly based on flexible and stretchable circuits encapsulated in a polymer material (silicone, polyurethane). Due to the conformability of the system, integrating mechanical switches like push buttons, etc. to switch on/off and control the device is not the best solution. In this master thesis, the student should investigate possible solutions to overcome this issue. If one thinks about non-mechanical switches/controls/.., capacitive, inductive based switches can be a solution together with more complicated control means like Bluetooth or NFC, controlled by a user interface running on a smartphone.

Objectives:

The student should create a platform that is able to control a wearable electronic system encapsulated in a polymer. This means developing:

- A way to recharge an integrated battery by inductive charging.

- A way to switch on/off the system without mechanical switches.

- A way to control the system (reading out sensors or activating actuators) by means of a wireless protocol (e.g. Bluetooth, NFC) communicating with a user interface running on a smartphone.

The system should be easy adjustable in a way that integrating more sensors or actuators doesn’t need a complete reprogramming of the driving electronics/user interface.
