The goal of this project is to realize a 3 cm x 3 cm pressure sensor matrix in a stretchable technology, as schematically shown on the left. This high-resolution sensor consists of 9 sensor points per square cm. The total thickness should preferably be less than 1 mm.
One aspect of the thesis will be the design and the fabrication of the pressure sensor matrix in a high-resolution, stretchable techology. After fabrication of the electronics circuit on a flat substrate, the pressure sensor layer will be added, the circuit will be embedded in its final insole polymer and it will be deformed to its final 2.5D shape.
Apart from the physical realization of the pressure sensor matrix itself, it is also needed to develop a low-power electronic circuit enabling the operation and the read-out / visualisation of the sensor. The electronic design encompasses an intelligent driving system, sensor read-out, signal processing, and some peripheral electronics like power supply and wireless communication. The software to visualize the pressure distribution can be written for a PC, smartphone or tablet.
The thesis will be divided into several subtasks:
