Riassunto
Conformable electronics represents a rapidly emerging field aimed at developing ultra-thin and flexible devices capable of seamlessly integrating with curved or soft surfaces, such as human skin or biological tissues. This technological advancement enables applications in wearable sensors, biomedical devices, and skin-integrated circuits, where traditional rigid electronics are not suitable. This thesis explores the fabrication of ultra-thin, flexible, and conformable field-effect transistors (FETs) based on molybdenum disulfide (MoS2), a two-dimensional semiconductor material. The research follows a multi process approach, combining chemical vapor deposition (CVD) for MoS2 growth, inkjet printing for electrode deposition, and the integration of freestanding dielectric layers to achieve truly conformable devices.
The fabricated transistors were electrically characterized and the statistical value of field effect mobility, threshold voltage, subthreshold slope and ratio between maximum and minimum current were extracted. The possibility to integrate resistive load inverters, buffers and three-stage ring oscillators was also explored. The results show the potential of this approach, but also highlight its limitations and defects, leaving room for further improvements.
