Autonomous and energy efficient wireless sensor platforms

In recent time, wireless technologies have been rapidly developing, paving the way to the spreading of mobile technologies. Indeed, several wireless applications grew up for short-range, point-to-point communications, long-distance cellular phone systems and internet applications. Moreover, the peculiarity of wireless systems for contactless communications over distance has allowed the development of emerging applications, such as wireless sensor in order to monitor several physical parameters in applications where electro-mechanical systems must interact with the environment. These devices are typically low-cost, low-power and tiny devices, equipped with limited sensing, data processing and wireless communication capabilities, as well as power supply elements.
