An important part of ERDEC defense research programs is the investigation of new technologies that could ameliorate specific problems in biological defense. A recent report ERDEC-TR-25S, June 1995 discussed the application of electric field technology to such problems. The present report is the second in a new series of documents which will seek novel applications of existing and emerging technology, including electric field and electrostatics technology, to biological defense scenarios. The present work demonstrates that typical drying times for water containing or water wetted materials such as fabrics and possibly biological matter can be decreased by factors of up to about 10 in electric fields ranging up to above 7 kVcm. Measured electric currents over this range increase by 3 to 4 orders of magnitude. Recommendations are given for a limited series of simple experiments in which living organisms would be exposed to electric fields of varying strength in air, and the results analyzed. Such measurements have never been done before.
