Flexible/stretchable sensors required to tolerate large deformations without loss of function.
•Integration with irregular/frequently deformed interfaces(e.g.,human tissues[1],joints of instruments[2],soft surgical robots).
•Conductive elastomeric inks are a popular choice for making these.
•Obtained by mixing elastomers (e.g.,PDMS[3] and polyurethane [4]) with conductive fillers (e.g., carbon black(CB)[5], graphene[6] and carbon nanotubes (CNT)[7]).
•Low-cost and easy to produce.
•Suitable for large-scale fabrication of stretchable electronic devices through additive manufacturing (e.g., stencil and screen printing).
