Abstract: Disclosed is a system and method for determination of the viscoelastic properties of a viscoelastic substance based on the type of non-mechanical forces which drive the viscoelastic substance inside a channel. These forces may comprise capillary, gravitational, electric, magnetic, or any other type where neither a pump nor any relative velocity between solid surfaces is needed to induce the transport of fluid medium. As a result, the design of the system remains simple, and the system is capable of yielding results devoid of noise produced by mechanical forcing. The present disclosure a general analysis describing extraction of viscoelastic properties by observing flow-systems driven by any non-mechanical means, including capillary force and electro-osmotic force. Such time-dependent penetration depth may be recorded by optical, electrical or mechanical means and may further include the use of a computing device.
