发明名称 Electronic indicator for monitoring efficacy of a cleaning cycle
摘要 An electronic indicator includes artificial soil and sensor. An electrical characteristic of the electronic indicator can vary due to a change in the volume of the artificial soil. In some embodiments, the electrical characteristic of the electronic indicator can be measured by an electrical characteristic reader and used to determine efficacy of a cleaning cycle.

主权项 1. An electronic indicator to monitor efficacy of a cleaning cycle, comprising: a barrier layer comprising a first dielectric material, the barrier layer having a first barrier surface and a second barrier surface, the first barrier surface being opposite to the second barrier surface; a volume of wash-removable artificial soil disposed on at least a portion of the first barrier surface; and a sensor having a first major sensor surface and an opposing second major sensor surface, wherein the first major sensor surface is adjacent to the second barrier surface, and wherein an electrical characteristic of the electronic indicator varies in response to a change in the volume of the artificial soil.
