No-Power Oscillating Sensor

No-power oscillating sensor technology consists of a wireless, completely passive (self-powered) analog voltage amplitude-to-RF converter for real-time, harsh environment measurements. Currently, wired and battery-operated sensors are the most common sensors used in harsh or contested environments. This technology addresses the shortcomings of wired sensors with wireless, in-place measurements based on RF technology. This technology is inherently self-powered and features an extremely long working life. It uses the RFID sensor as a frequency-modulated transmitter of analog voltage amplitude. Wireless transmission is achieved through RF transmission using tuned polymer-derived ceramics (PDC) as the capacitive dielectric, and wireless transmission and is the transduction mechanism for an RFID sensor. The novelty of this technology is to use the RFID sensor as a frequency-modulated transmitter of analog voltage amplitude. The VCO provides the capability to efficiently use different types of analog sensors such as thermocouples, voltage, or pressure.
