Conventional techniques for thermal conductivity measurements can lead to unreliable results when applied to nanostructures because heaters and temperature sensors needed for the measurement cannot have a negligible size and therefore perturb the result. In…
We discuss processes for the fabrication of devices for thermoelectric generation, based on silicon nanostructures. The main issue that we address is the design and development of fabrication processes for devices exploiting a large number…
This work presents a fully digital implementation of an audio front-end for portable applications developed in a low-power perspective.Such platform acquires audio samples through a four digital Pulse Digital Modulation (PDM) microphones array andimplements two-channel…
Voice Activity Detectors (VADs) are used to enhance performances and to reduce the activation rate of speech recognition and key-word spotting applications. The last aspect is crucial for portable applications because it allows to save…
Nowadays Voice User Interfaces (VUIs) have become popular thanks to their easiness of use that makes them accessible to the elderly and people with disability. Nevertheless, their use in embedded systems for the realization of…
