Radio frequency (RF) energy harvesting systems are enabling new evolution
towards charging low energy wireless devices, especially wireless sensor

networks (WSN). This evolution is sparked by the development of low-
energy micro-controller units (MCU). This article presents a practical

multiple input multiple output (MIMO) RF energy-harvesting platform for
WSN. The RF energy is sourced from a dedicated access point (AP). The
sensor node is equipped with multiple antennas with diverse frequency
responses. Moreover, the platform allows for simultaneous information and
energy transfer without sacrificing system duplexity, unlike time-switching
RF harvesting systems where data is transmitted only for a portion of the
total transmission duty cycle, or power-splitting systems where the power
difference between the information signal (IS) and energy signal (ES) is
neglected. The proposed platform addresses the gap between those two.
Furthermore, system simulation and two energy scheduling methods between
AP and sensor node (SN) are presented, namely, Continuous power stream
(CPS) and intermittent power stream (IPS).
