Abstract
Official abstract text for this publication.
An electronic sensing system has a transceiver with input and output pads, an excitation circuit connected to the output pad, and a detection circuit connected to the input pad. An electrically-conductive sensor patch has an electrical state that changes with exposure to a corresponding environmental factor. The detection circuit detects an electrical state of the input electrical-connection pad in response to the excitation signal and the electrical state of the sensor patch. A stack of one or more layers in order is disposed over the sensor patch in the detection region. Each layer is susceptible to a respective environmental factor, so that the sensor patch changes electrical state in response to exposure of the layer stack to the respective environmental factors of the one or more layer(s) in the selected order and subsequent exposure of the sensor patch to the corresponding environmental factor.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electronic sensing system, comprising: a substrate with a detection region; a transceiver formed on a transceiver substrate separate from the substrate and affixed to the substrate, the transceiver including: an output pad for making an electrical connection; an excitation circuit adapted to provide an excitation signal to the output pad; an input pad for making an electrical connection; a detection circuit connected to the input pad; and…
