This paper reports measurements of elastic moduli for hydrogel microcantilevers by employing a stylus profilometer. First, hydrogel microcantilevers were fabricated with poly(ethylene glycol) diacrylate (PEGDA) using a polydimethylsiloxane (PDMS) cantilever mold via UV crosslinking along with capillary force induced filling into the mold. The length of fabricated hydrogel microcantilevers was controlled by cutting them using a razor blade after crosslinking while other dimensions were determined by the PDMS cantilever mold. Finally, crosslinked hydrogel microcantilevers were scanned with a stylus profilometer to examine their out-of-plane bendings at a fixed contact load. By applying cubic root fitting to the cantilever deflections, elastic moduli of tested hydrogel microcantilevers were extracted. PEGDA Mw 250 and 575 with 1 wt% of photointiator (phenylbis (2, 4, 6-trimethylbenzoyl) phosphine oxide) were used as testing materials. Commercial silicon microcantilevers were used to calibrate the stylus forces and other possible error sources were provided.
