We investigate electro-mechanical contributions to the low frequency dielectric response of biological cells in colloidal suspension. Prior simulations of biological cells in colloidal suspension yield maximum dielectric constant values about 103 in magnitude as the frequency of applied electric fields drops below the kHz range. Experimentally measured relative dielectric values in yeast cells , on the other hand, have maximal values up to 107 - 108 . We consider both electrical and mechanical energy stored in cellular suspension and show that low frequency mechanical contributions can give rise to dielectric constant values of this magnitude.
Comments: 18 pages. Part of a different analogy to bio phyics dielectric constants explored by the author with Dr. Patrick Xie and Dr. James Claycomb at the Texas center for super conductivity, Houston, Texas, in early 2002.
