Embedded 3D Printing of Strain Sensors within Highly Stretchable Elastomers

A new method, embedded-3D printing (e-3DP), is reported for fabricating strain sensors within highly conformal and extensible elastomeric matrices. e-3DP allows soft sensors to be created in nearly arbitrary planar and 3D motifs in a highly programmable and seamless manner. Several embodiments are demonstrated and sensor performance is characterized. As a service to our authors and readers, this journal provides supporting information supplied by the authors.
