Passive sensor system powered by wireless power transmission

Posted by Maria from Instituto de TelecomunicaçõesResponsive · Patents for licensing · Portugal

Summary of the technology

Network of wireless and passive sensors (without batteries), using a set of unique sensors which use a frequency for the data transfer (obtained by sensors) and another frequency for the reception of energy that is emitted by transmitters that power the sensors. For this, only a central data reception and wireless transmission structure is required which communicates with each of the sensors independently. These sensors have low power consumption and high data rates (up to 960 Mb/s).

CONTEXT

Wireless sensors, which transmit the collected information without the need of wiring, have gainedincreasingcommercial importance. These sensors can be used in a wide range of situations, fromenvironmentalmonitoring to farm and industrial control. However, most sensors still need to use batteries, which increases maintenance and environmental costs.

The presented sensors are an alternative since they do not require any type of battery and receive energy through a specific frequency emitted by an energy transmitter. These passive sensors gain even more relevance if sensor networks are formed, in which several nearby sensors detect and transmitenvironmentaldata. These sensors can have the capability of reusing ambient electromagnetic waves to perform the communication (e.g. Wi-Fi, Bluetooth,LoRa, etc.)

APPLICATIONS

This passive sensor system can be used in a wide range of applications, such as:

COLLECTION OF ENVIRONMENTAL DATA - e.g. farm fields, insidebuildings

ACCESSES CONTROL - e.g. parking lots,buildings

USES REQUIRING HIGH TRANSMISSION RATES - e.g. audio or videosensors

BENEFITS

Compared to traditional sensors:

LOWER COST: no batteries, of any kind.

INCREASED CONVENIENCE: no batterycharge orchange, nowiring.

Compared to other passive sensors:

LOWER POWER CONSUMPTION

HIGHER DATA TRANSMISSION RATES: up to 960Mb/s.

POSSIBILITY TO USE AMBIENT ELECTROMAGNETIC WAVES: Wi-Fi, Bluetooth,LoRa, etc.
