Researchers: We've developed a self-destructing phone! Samsung: Pfft...we're not impressed.
The self-destruct mechanism relies on an expandable polymer layer that can rapidly expand to around seven times its original volume when heated to temperatures above 80 degrees C. The heat that triggers the polymer expansion comes from heater electrodes that could draw power from the battery of a smartphone or laptop. Full details of the study will be published in an upcoming issue of the journal Advanced Materials Technologies.
