Title: PRESSURE SENSOR INCLUDING A PRESSURE SENSITIVE MATERIAL FOR USE WITH CONTROL SYSTEMS AND METHODS OF USING THE SAME
Abstract:
Pressure sensors for sending a plurality of control messages to a system controller are disclosed herein. An example pressure sensor may include: a base; at least first and second conductors; a pressure sensitive material at least partially intervening between the first and second conductors; a memory; a clock; and a processor. The pressure sensitive material may have a composition configured to continuously change at least one electrical property. The processor may be configured to determine a first electrical property using the first and second conductors, associate the first electrical property with a time from the clock and write the first electrical property and the time to the memory. The processor may also be configured to calculate a time-based change in the first electrical property, correlate the time -based change with at least one of the control messages and communicate the at least one of the control messages to the system controller.
