Electronic Sensor Technology

SensorBit Systems is developing and commercializing a revolutionary technology that is capable of detecting trace amounts of complex chemical vapors in seconds. Due to its low power consumption and small form factor, this sensor system enables the implementation of compact, lightweight, and portable product applications. More so than any other technology, SensorBit technology has the potential to change that and provide smart, light-weight sensors in many more areas. With the SensorBit technology, versatility doesn't have to have a large size, high precision doesn't have to have a high price tag, and portability doesn't have to be specialized.


The SensorBit technology consists of an array of sensors, each treated with one of a variety of receptors, causing each sensor to respond electrically to a given vapor in a unique fashion. The combination of all signals produced by the sensor array generates a characteristic digital signature for a given vapor. The system is trained to recognize a digital signature of interest within a vapor compound. This type of device is sometimes referred to as an "electronic nose," due to its operational similarity to a biological nose.


Compatible with CMOS Production


SensorBit Systems' sensor is based on a revolutionary new class of chemical sensor microarray on a chip, which promises to be unique in the market due to its low power consumption and small form factor. This sensor system is uniquely suited for compact, light weight, and portable product applications, as well as applications requiring low power. The sensor array is compatible with standard CMOS silicon processing and is easily embedded onto circuit boards or directly into silicon chips,
Sensorbit Technology easily integrates into standard CMOS production

  • Additional functionality can be added to the 4-T cell
    • Logic, Memory, Power distribution, Wireless or Wired Networking, etc.
opening integration possibilities such as wireless communication, networking capability or coupling to RFID technology.

The technology utilized by SensorBit will provide the industry with an integrated chip that has improved sensitivity and selectivity, as well as low cost for mass production. With the introduction of this technology, we expect the monolithic sensor microarray on a chip to replace separate component instruments in much the same way integrated circuits have replaced large electronic systems, opening new mass markets. The sensor array could enable a single sensing chip to simultaneously detect multiple dangerous fumes such as smoke, carbon monoxide, natural gas, and propane. Simple integration, low cost, and small form factor of the sensor array will open possibilities of cell phone integration where common hazards are constantly monitored with a device in the pocket, testing for environmental hazards such as toxic gases, hazardous fumes, hazardous gas leaks, cleaning solvents, air quality, and air pollution elements.




SensorBit uses a combination of CMOS technology with organic materials for the detection of polar and non-polar analytes. This technology offers a significant step forward because of its small form factor, low manufacturing cost, and high detection sensitivity and versatility, expanding the areas of utilization.
Compliment of measurement routes possible
  • Silicon Current, responding to polar analytes
  • Organic Current, responding to non-polar analytes
The signal analysis is improved with the design because information regarding the interaction between the analyte and the cell can be seen from responses in the silicon current and the organic resistance. The benefit is seen in increased information for qualitative and quantitative analyses and in a reduced calculation burden. This presentation will report on technology design and manufacturing and will cover the fundamentals of the design; the status of the development effort, including the measurements and interpretation of the data. Stability of the organic materials and measure-ments of polar organics and non-polar molecules will be demonstrated.
