A touch sensor is an essential component in meeting the growing demand
for human-machine interfaces. These sensors have been developed in
wearable, attachable, and even implantable forms to acquire a wide range
of information from humans. To be applied to the human body, sensors are
required to be biocompatible and not restrict the natural movement of
the body. Ionic materials are a promising candidate for soft touch
sensors due to their outstanding properties, which include high
stretchability, transparency, ionic conductivity, and biocompatibility.
Here, this review discusses the unique features of soft ionic touch
position sensors, focusing on the ionic material and its key role in the
sensor. The touch sensing mechanisms include piezocapacitive,
piezoresistive, surface capacitive, piezoelectric, and triboelectric and
triboresistive sensing. This review analyzes the implementation hurdles
and future research directions of the soft ionic touch sensors for the
transformative potential.20 Feb 2024Review(s) Completed, Editorial Evaluation Pending 02 Mar 2024Reviewer(s) Assigned
