The node operates at distances up to 17 m from a 2 W UHF carrier. RF power transfer allows operation when common energy scavenging sources (e.g., sun, heat, etc.) are not available, while the DASH7 communication protocol makes it fully compatible with a standard IoT infrastructure. An optimized energy-harvesting module has been designed, including a rectifying antenna (rectenna) and an integrated nano-power DC/DC converter performing maximum-power-point-tracking (MPPT). A nonlinear/electromagnetic co-design procedure is adopted to design the rectenna, which is optimized to operate at ultra-low power levels. An ultra-low power microcontroller controls on-board sensors and wireless protocol, to adapt the power consumption to the available detected power by changing wake-up policies. As a result, adaptive behavior can be observed in the designed platform, to the extent that the transmission data rate is dynamically determined by RF power. Among the novel features of the system, we highlight the use of nano-power energy harvesting, the implementation of specific hardware/software wake-up policies, optimized algorithms for best sampling rate implementation, and adaptive behavior by the node based on the power received.

Non-contact probing can provide an important contribution for testing complex Systems-on-a-Chip (... more Non-contact probing can provide an important contribution for testing complex Systems-on-a-Chip (SoC), Systems-in-a-Package (SiP) and Through-Silicon-Vias (TSV) interconnections. This paper demonstrates the feasibility of wireless testing by capacitive coupling between a cantilever probe card and a pad. In particular a scheme of an I/O pad suitable for both contact and contactless probing is proposed.
