Wireless power transfer provides a most convenient solution to charge devices remotely and
without contacts. R&D has advanced the capabilities, variety, and maturity of solutions …

In recent decades, micromachined ultrasonic transducers (MUTs) have been investigated as
an alternative to conventional piezocomposite ultrasonic transducers, primarily due to the …

Resonance-based wireless power delivery is an efficient technique to transfer power over a
relatively long distance. This technique typically uses four coils as opposed to two coils used …

Inductive power transmission is widely used to energize implantable microelectronic devices
(IMDs), recharge batteries, and energy harvesters. Power transfer efficiency (PTE) and …

All the wireless power transfer (WPT) systems share a similar configuration including a
power source, a coupling system, a rectifying circuit, a power regulating, and charging …

As the most successful neural prosthesis, cochlear implants have provided partial hearing to
more than 120000 persons worldwide; half of which being pediatric users who are able to …

The development of implanted devices is essential because of their direct effect on the lives
and safety of humanity. This paper presents the current issues and challenges related to all …

Inductive coupling is a viable scheme to wirelessly energize devices with a wide range of
power requirements from nanowatts in radio frequency identification tags to milliwatts in …

The operation of wireless power transfer systems with multiple transmitters (TXs) or
receivers (RXs) is investigated. With multiple TXs or RXs in a limited space, couplings occur …

It is shown that the distance of wireless power transfer is significantly increased by placing
intermediate resonators (repeaters) between transmitter and receiver. The guidelines are …
