MEMS-based monitoring
First Claim
1. A monitoring system comprising:
- a monitoring device including;
a Micro-ElectroMechanical Systems (MEMS)-based sensing device configured to sense a property of at least one of;
an area or an object, distinct from the sensing device, to which the monitoring device is affixed;
a transmitter, distinct from the sensing device, configured to transmit a signal based on the property and an identity of the monitoring device, wherein the MEMS-based sensing device varies at least one of;
a frequency, an amplitude, or a phase of the signal with the property, and wherein the signal is transmitted either continuously or periodically according to a set time period;
a processing module configured to periodically switch between two states to adjust at least one of;
the frequency, the amplitude, or the phase of the signal to identify the monitoring device; and
a power module configured to provide power to the sensing device and the transmitter.

Abstract
A solution for monitoring a property of an object and/or an area using a Micro-ElectroMechanical Systems (MEMS)-based monitoring device is provided. In an embodiment of the invention, the MEMS-based monitoring device includes a MEMS-based sensing device for obtaining data based on a property of the object and/or area and a power generation device that generates power from an ambient condition of the monitoring device. In this manner, the monitoring device can operate independent of any outside power sources or other devices. Further, the monitoring device can include a transmitter that transmits a signal based on the property. The monitoring device can be used to monitor a moving component of a machine, and can be integrated with a health monitoring system of the machine using one or more relay devices.
