Abstract

A device, method, and process for fabricating a sensor comprising a polymer-based microfluidic sensing platform for detecting distributed loads. The sensing platform comprises a polymer microstructure; and an electrolyte-enabled distributed transducer. The electrolyte-enabled distributed transducer comprises: a microchannel formed in the unitary polymer microstructure configured to hold an electrolyte; and an electrode underneath the microchannel. The microfluidic sensing platform is configured to detect distributed loads at the micron-millimeter scale.
