Abstract

A multi-layer pad for monitoring a patient includes first and second knitted fabric layers. The first knitted fabric layer includes first and second non-conductive bands and a first conductive strip that extend in a first direction. The first conductive strip is between the first and second non-conductive bands and is in contact with a power source. The second knitted fabric layer includes third and fourth non-conductive bands and a second conductive strip that extend in a second direction. The second conductive strip is between the third and fourth non-conductive bands and is in contact with the power source. A spacer is between the first and second knitted fabric layers. An impermeable cover layer encompasses the knitted fabric layers and the spacer. Upon application of force to the multi-layer pad, the first conductive strip is configured to move into close proximity with the second conductive strip and complete an electrical circuit.
