“…These values are the maximum output power obtains in each part when the load resistor is 3.3kΩ. The achievement is perform better and obtained higher result compared to the development in [18] which using similar types of transducer. From these results, it is confirmed that the efficiency of the system is increased when the MIMO arrangement of the transceiver is applied to the system.…”

<span>This paper presents a development of Acoustic energy transfer (AET) system through the air medium by implementing a Multiple Input-Multiple Output (MIMO) arrangement of transducers to transmit energy. AET system allows power to be transmitted without wire connection. The MIMO system is proposed in this paper to increase the efficiency of the transmitting power by multiplying the received power. The simulation and experimental works are carried out using a Class E power converter and the obtained results are analyzed accordingly. Based on the experimental results, the 18.57mW output power is obtained at 40kHz operating frequency when triple transducer is used. It contributes to 30.96% efficiency to the power transfer system.</span>

“…Single input-output transducer has been developed in [18] shows a lack of output power received by the transducer, see Figure 1. Thus, this paper proposes a new arrangement of transducer position so that the received power can be multiplied using multiple-input multiple output (MIMO) transducer, see Figure 2.…”

“…Furthermore, prototypes and simulations presented by Tseng et al [74] and Nagaya et al [56] have shown that uWPT efficiency can be drastically improved by using multiple receiving elements instead of one. For example, Zaid et al [83] have achieved a power conversion efficiency of 34% and anticipate further improvements based on thermal insulation.…”

“…This technology is not new and has primarily been used in engineering and medical applications such as powering medical implants and IoT sensors. Airborne ultrasound WPT has a small form factor (a few centimetres) [32], can achieve power conversion efficiencies of the order of 35% [83], and can be encoded with additional information enabling control and data transfer applications beyond simple switching on/off sensors and actuators [67]. Consequently, we argue that ultrasound WPT is a strong candidate for HCI applications.…”

“…The performance of an acoustic power transfer (APT) system depends on several factors, including the material properties of the piezoelectric transducers [7] and the size and geometry of these transducers. For example, [8] optimized the converter to reduce the system's losses. Another crucial factor that significantly affects the system's performance is impedance matching.…”

This paper presents a study on improving the performance of the acoustic piezoelectric transducer system in air, as the low acoustic impedance of air leads to suboptimal system performance. Impedance matching techniques can enhance the acoustic power transfer (APT) system’s performance in air. This study integrates an impedance matching circuit into the Mason circuit and investigates the impact of fixed constraints on the piezoelectric transducer’s sound pressure and output voltage. Additionally, this paper proposes a novel equilateral triangular peripheral clamp that is entirely 3D-printable and cost-effective. This study analyses the peripheral clamp’s impedance and distance characteristics and confirms its effectiveness through consistent experimental and simulation results. The findings of this study can aid researchers and practitioners in various fields that employ APT systems to improve their performance in air.
