Samba Sensors is a developer and manufacturer of advanced fiber-optic technology for pressure measurements.
Company expertise is focused on the design and development of ultra-miniature pressure transducers and control systems, primarily for applications in the life sciences. Samba Sensors collaborates closely with several leading medical research teams and companies throughout the world.
The Samba sensors measurement technology is applicable in basically all kinds of life science applications and is extremely accurate for measurements of physiological parameters like systolic blood pressure, intravascular blood pressure and intracranial pressure during trauma. Samba sensors are used in humans as well as in both small and large animal models but most commonly used for blood pressure in mouse and intracranial pressure (ICP) in rat.
History
Samba Sensors AB was founded in 1992 to commercialize a novel pressure sensor developed at Chalmers University of Technology in Gothenburg, Sweden. The original transducer was designed by Prof. Olof Engström to measure pressure under the extreme conditions existing in the cylinders of Volvo combustion engines. Since 1998, company has continued to develop the generic technology, with a focus on ultra-miniature catheters for preclinical and clinical research. Samba Sensors AB entered bankruptcy in October 2012, in January 2013, its latest patent for pressure measurements in the human backbone was transferred to the Canadian company FISO Technologies inc.
Development and patents
The Samba transducer comprises a sensor element mounted on the tip of an optical fiber. The functional principle is that light passes through the fiber and is reflected in a cavity inside the sensor element. The height of the cavity is relative to the external pressure that the sensor element is being exposed to. When the pressure surrounding the sensor element is changing, the reflected light signal will change. The Samba Control Unit receives the reflected light signal and processes it to a readable pressure value.
The transducer is physically designed as a pressure-sensitive optical interferometer according to the Fabry–Pérot principle. The sensor element is produced in silicon using microstructure processes originating from the semiconductor industry. The optical fiber is made of glass and has special coatings. The Samba Preclin transducer is an example of a MOMS (Micro Optic Mechanical System) device.
Measurement of the surrounding static or dynamic pressure is possible in both gases and liquids.
The Samba technology is a patented solution for pressure measurement based on fiber-optics.
Samba Sensors' quality management system is approved according to ISO 9001:2000 and ISO 13485:2003 and is adapted to comply with the U.S. Food and Drug Administration (FDA) regulations in the USA.
