power
transfer (WPT)
plays an important
role in medical
devices that
require contactless energy transfer
for either direct powering or recharging
their small batteries. Miniaturizing
medical devices and improving
their WPT link robustness against
different variations (e.g., distance,
alignment, and load changes) also

demands an efficient and adaptive
power-management IC (PMIC) to
convert the incoming ac power carrier
into one or multiple usable dc
voltage supplies. This article summarizes
the key techniques for WPT
and PMIC design. It discusses different
modalities for WPT, including inductive,
ultrasonic, capacitive, and
magnetoelectric (ME) methods, with
a focus on their applicability in different
types of medical devices with
different dimensions, implantation
depths, and power requirements. It
is concluded that ultrasonic and ME
modalities are suitable for WPT to
deeply implanted small devices with
low power consumption, while inductive
and capacitive methods are
more suitable for WPT to large implants
with shorter depth and higher
power consumption. This article
also summarizes different PMIC
techniques for inductive WPT, particularly
conventional voltage mode
and more recent current-mode (and
reconfigurable) techniques, with
an emphasis on their suitability
for different input voltage and loading
conditions.
