Non-invasive AC Current Sensors are a good way to measure real consumption without altering the electrical composition of the elements to be analyzed. They work by magnetic induction, so that the field generated in the cable, used to power the device, induces a current in the transformer integrated in the sensor. In this way we can know what the current is in the power cable and therefore the actual consumption of the device to be measured.

Quantification of biological or biochemical processes are critical for medical, biological and biotechnological applications. However, the conversion of biological information to an electronic signal to facilitate subsequent processing is a challenge due to the complexity of the connection of an electronic device directly to a biological environment.

Biosensors are attractive devices for analyzing the content of a biological sample due to the direct conversion of a biological event into an electronic signal.

A biosensor consists of a biological recognition element, a transducer and an electronic system. In a complex sample, the biological recognition element is able to discriminate between the various components therein and interact with the compound to be analyzed. Also called analyte. Once produced the interaction the transducer converts the energy produced by this into an electrical signal. Finally the electronic records and processes the signal.
