Anti-slip cushioning sensor mat

An alarm system, comprising:

• an anti-slip cushioning sensor mat configured to detect the presence of a subject and send a signal when the subject is present, wherein the anti-slip cushioning sensor mat comprises:
• a PVC leather layer;
• a polyurethane foaming layer disposed below the PVC leather layer;
• a sensitive layer disposed below the polyurethane foaming layer and configured to sense whether the subject is present and output an alarm signal when the subject is present;
• and
• a rubber layer disposed below the sensitive layer,
• an alarm apparatus connected to the sensitive layer and configured to receive the alarm signal and sound alarm.

A method of making an anti-slip cushioning sensor mat, comprising the following steps:

• putting PVC leather into a mold;
• injecting polyurethane mixed foaming material into the mold to generate a complex multilayer structure including a PVC leather layer and a polyurethane foaming layer;
• attaching a sensitive layer to the polyurethane foaming layer;
• and
• adhering a rubber layer to the sensitive layer.
