Sensor PCB

In order to test and monitor vibration, pressure, power, acoustics, load, and shock in development and research as well as industrial applications, PCB manufactures sensors that are utilized by design engineers & predictive maintenance specialists. There are several definitions of what a sensor is, but I’d like to say that it’s an input device that outputs a signal relating to a certain physical quantity (input).


The technology of printed circuit boards (PCBs) is well-established and widely available worldwide. This method has also been used to create electrical components, including electrodes for various biological & chemical sensors. This fabrication method is an excellent choice for patterning the electrodes and electrical components of biosensors due to its high reproducibility, which is attained by long-lasting standard processes, and low cost, which results from the availability of competitive manufacturing services.

The use of this method in the construction of sensing platforms makes it easier to combine electronics, microfluidics, and biosensors. The fundamental ideas and developments in printed board circuit technology are covered in this review study.  A summary of current developments in the creation of PCB-based immunosensors is also provided. Finally, the difficulties and prospects for PCB-based sensors are described.

Classification of Sensors

Different writers and professionals have categorized sensors in a number of different ways. Some are relatively straightforward, while others are intricate. An expert in the field may already use the classification of sensors that follows, but it is very straightforward.

The sensors are separated into Active and Passive categories in the first classification. Active sensors are those that need an external power signal or an excitation signal.

On the other hand, passive sensors produce an output response without the need for any external power signals.

The other classification method is based on the sensor’s method of detection. Electric, biological, chemical, radioactive, and other methods of detection are some examples.

Analog and digital sensors make up the last two categories of sensors. In relation to the amount being measured, analog sensors produce an analog output, or a constant output signal (often voltage but occasionally other parameters like Resistance, etc.).
