Modulus‐tunable composite micropillars are presented by combining replica molding and selective inking for skin adhesive patch in “ubiquitous”‐health diagnostic devices. Inspired from hierarchical hairs in the gecko's toe pad, a simple method is presented to form composite polydimethylsiloxane (PDMS) micropillars that are highly adhesive (∼1.8 N cm −2 ) and mechanically robust (∼30 cycles).
