Flexible and Stretchable Electronic Skin with High Durability and Shock Resistance via Embedded 3D Printing Technology for Human Activity Monitoring and Personal Healthcare

Abstract: Electronic skin (e‐skin) integrating pressure sensors and strain sensors has shown great potential applications in smart robotics and healthcare monitoring for their flexibility and wearability. However, making the sensor low cost and highly durable for industrialization and commercialization is still a problem to be addressed. An embedded 3D printing technology is developed based on novel thermosetting printing ink which is prepared using the Ecoflex and carbon nanoparticles. The properties of the printing in… Show more

“…Flexible and stretchable sensors are attracting significant interest in a wide range of applications including health monitoring, diagnostic devices, soft robotics, and electronic skins. [ 1–6 ] Piezoresistive sensors, one of the main types of sensors, change their resistance in response to mechanical deformation and have demonstrated a number of applications in monitoring strain, [ 4–8 ] pressure, [ 6,7,9 ] flow, [ 10–12 ] and temperature. [ 4,13,14 ] To meet the requirements for both human motion detection and biosafety, flexible sensors should be biocompatible.…”

“…In this regard, different types of elastomers such as polydimethylsiloxane (PDMS) or hydrogels such as polyvinyl alcohol (PVA) hydrogels have been extensively used as the flexible substrate/matrix. [ 15–18 ] While the flexible substrate/matrix, in most cases, determines the mechanical properties of the sensors, conductive materials including carbon nanoparticles, [ 6 ] carbon nanofibers (CNFs), [ 15,19 ] carbon nanotubes (CNTs), [ 20 ] graphene, [ 5,21 ] silver nanowires (AgNWs), [ 19,22 ] and silver nanoparticles [ 23 ] have been successfully used as the sensing elements. Different techniques have been developed to incorporate conductive elements with the flexible substrate/matrix.…”

“…Flexibility, stretchability and light‐weight of wearable electronics, as the key factors determining the comfort level of users and the portability of devices, have drawn tremendous attention across the world for developing finger/glove sensors with such characteristics 122‐125 . The common flexible strain sensors are normally based on resistive sensing 123,126‐137 or capacitive sensing, 138,139 whose output signals can dynamically respond to the variation of applied force or strain under continuous motions. A finger‐bending strain sensor is presented using stretchable gallium‐based conductors, as indicated in Figure 3C 140 .…”
