Biosensors have found an increase in popularity across a wide variety of industries in recent years. From healthcare to ecological studies to drug development and delivery, Biosensors are seemingly everywhere. Did you know that biosensors rely on increasingly intricate micromachine parts? That’s right, without expert microfabrication manufacturers, like Citrogene, advancements in biosensors would be inhibited greatly.

In this post, we’ll examine some of the types of biosensors that are used in various industries. Let’s get started.

Types of Biosensors

Biosensors comes in all different shapes, sizes, utilities, and functionalities. Biosensors are classified based on the sensor device as well as the biological material involved in the analysis. Below, we’ll examine several different types of biosensors and detail what makes each unique.

Electromechanical Biosensors

Electromechanical biosensors are based on the reaction of enzymatic catalysis that consumes or generates electrons. Electromechanical biosensors are classified into four types: amperometric, potentiometric, impedimetric, and voltammetric.

Physical Biosensor

Psychical biosensors are the most fundamental as well as most widely use sensors. Physical biosensors find uses in inspecting the human mind, such as hearing, sight, and touch. A device that is able to detect reactions to physical stimuli can be categorized as a physical biosensor.

Optical Biosensor

As the name implies, an optical biosensor is a device that uses an optical measurement principle. More often than not, optical biosensors make use of fiber optics as well as optoelectronic transducers. Optical biosensors are classified into two type’s namely direct optical detection biosensors and labeled optical detection biosensors.

Wearable Biosensors

Wearable Biosensors is a digital device that is worn on the human body. Examples include smart watches, smart shirts, blood pressure monitoring devices, heart monitoring devices, etc. Wearable biosensors are almost commonplace thanks to smartwatches and fitness trackers. Everyday people are able to access and improve their health thanks to wearable biosensors.
