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.
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.
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 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.
