Sensing solutions

Sandvik offers polymer coated precision medical wire solutions which are used in sensor applications in vivo diagnostics and therapeutic procedures, where electrical signals or currents are conducted micro-invasively. The medical sensor device category comprises wire applications such as thermocouples, glucose sensors and electrical sensor devices.


EXERA® wire-based components which can be found in, for example, glucose-sensing solutions, help to improve everyday life and can even be life-changing. Katina has a glucose monitoring device. Check out her story.


A device based on thermo-electric operations used for the purpose of measuring temperature differences. It is comprised of two wires of different metals coupled at two points, and the temperature difference between the two points is developed and recorded in proportion to the corresponding difference of voltage being developed. Medical grade thermocouples are commonly used for the precise and accurate measurement of tissue temperature during ablation. They are widely used in treating tachycardia and atrial fibrillation and measuring the tissue temperature during radiofrequency ablation of cardiac arrhythmias.

Glucose Sensors

Used in Continuous Glucose Monitoring devices to measure blood glucose levels in real-time. The CGM device is comprised of three components, namely, the monitor, the transmitter and the sensor. The sensor is among the most critical and refined parts of the CGM, and its size is thinner than that of a needle. The process by which the sensor detects the glucose level is through glucose oxidase which helps in converting glucose to hydrogen peroxide. Electrical signals are generated when the hydrogen peroxide reacts with the platinum based sensor and reach the transmitter through a minute wire.

Electrical Sensors

Wires manufactured by Sandvik fall under two categories based on their applications:

Multi-electrode arrays

Used to transmit neural signals and are aligned in the form of multiple plates. One of the models for multi-electrode arrays is the Utah model which is used to study parallel information from the central nervous system and break down information conveyed by the peripheral nervous system concerning the control of the limb and muscle forces.


Electrodes which find their application in neuroscience under the field of electro-physiology. They find their application in the recording of the potential difference between extra-cellular fields in the nervous tissues. The structure of tetrodes consists of four minute electrodes. The tetrode wire generally finds its application in nerve stimulation research and making electrodes. This category of electrical sensor wires can find their application in various implantable medical devices used in cochlear implant and deep brain stimulation.
