“…The circuit topology is adopted based on a prominent rectifier voltage doubler, which revolves around two distinct components: the diode and the capacitor. The component value listed in Table 5 aligns with the approach proposed by Tafekirt et al [18] and Sathiyapriya et al [19]. Moreover, the prominent commercial Schottky diodes are compared between the SMS7630 and HSMS2852 series, as both are sufficient for the Wi-Fi frequency bands.…”

This study proposes an ultra-wideband antenna for ambient radio frequency (RF) energy harvesting applications. The antenna is based on a co-planar waveguide (CPW) transmission line and incorporates a rectangular slot as an antenna harvester. The proposed antenna utilizes an evolutionary design process to achieve impedance matching of the 50 Ω CPW feeding line over the desired frequency bands. A parametric study investigates CPW elements and rectangular slot size. The harvester antenna is then connected to the primary rectifier circuit of the voltage doubler to examine the signal characteristics. The antenna covers the Industry, Science, and Medicine (ISM) Wi-Fi bands of 2.45 GHz and 5 GHz, achieving a realized gain of 3.641 dBi and 4.644 dBi at 2.45 GHz and 5 GHz, respectively. It exhibits a relatively broad frequency ranging from 2.16 GHz to 6.32 GHz, covering the ultra-wideband fractional bandwidth (FBW) of 105%.

“…When the input voltage is too low, a boost circuit is required to amplify the output. As an example, a voltage doubling circuit is introduced in [10], which is used to harvest radio frequency (RF) energy. For the problem of how to effectively utilize the electric energy stored in the internal capacitance of piezoelectric harvester mentioned in the first section, several approaches have been analyzed in [11], such as Parallel-SSHI and Series-SSHI circuits.…”

In the field of self-powered microelectronics with low power consumption, piezoelectric materials that convert mechanical energy into electrical energy are a widely used energy source. In the previous studies, only a few analyses have been carried out in the scope of optimal energy management of the entire electronic system. In this paper, a simplified energy simulation model of the real-time behavior of a whole energy-autonomous system is proposed. Different operating modes such as sleep, normal and standby, by using the newest ultra-low power Bluetooth communication technology (Bluetooth 5.2) for wireless transmission of measurement data, are analysed. This model was implemented in Simulink using the Pulse-width modulation (PWM) circuit as the power management unit. Based on the simulation data, the value of the output power was predicted, as well as the operation process was designed accordingly to ensure that the system can operate at the lowest power consumption normally. The simulation results demonstrate that the combination of multilayer Lead zirconate titanate (PZT) plates after the rectifier can provide the energy requirements for the normal operation of a microchip. When the energy source is not active, the energy stored in the capacitor can guarantee the processing of at least one measurement cycle. The simulation of the model is then discussed by comparing it with the experimental data.
