Senstech: Reliable Thin-film Sensors for Medical Devices
In Medical Technology, the dependability and stability of sensor measurements is of utmost importance. For instance, an infusion pump must reliably detect when the infusion flow is blocked. Thin-film technology has a particular advantage here, as it allows for sensors to be applied directly to metal parts without creeping layers.
Versatile and Adaptive Technology
Senstech's sensors react to the deformation of their substrate and can thus measure various parameters such as force, displacement, pressure or torque. We carry a range of sensor elements for common applications, but we specialize in customer-specific developments. Since our sensors are manufactured completely in-house, we can deliver first prototypes quickly and cost-effectively.

Pressure Monitoring as a Common Application
In infusion pumps from Arcomed and another major manufacturer, our sensors monitor the pressure in the infusion tube. Insulin pumps for Diabetes patients use a sensor in a similar way. A more recent application is the measurement of fluid pressure in phacoemulsification systems for eye surgery. All these sensor elements were developed in cooperation with the respective device manufacturers and are directly integrated into their product design.
Reliable Hardness Measurement in Tocodynamometers
For several product generations, a manufacturer of labor detectors (tocodynamometers) has relied on sensors from Senstech. The sensor used for this purpose is part of our standard product range.

Swiss Quality and Know-how
Senstech was founded in 1984 and has a rich experience in the development and manufacturing of sensors. Some of our products for Medical Technology have been in production for over 20 years. In recent years we introduced modern production processes using ablation lasers. Thanks to local supply chains and redundant facilities we are a reliable supplier even in times of crisis. As an ISO 9001 and ISO 13485 certified company, we are very familiar with the regulatory framework of the industry.
Standard Force Sensor KB-011-0500
This universal sensor can be mounted to any surface with an M2.5 screw and is available with several force ranges.
Amplified Force Sensor KB-011-0300
Thanks to its on-board amplifier this sensor can provide a 0-10V output signal without any extra circuitry.
Square Force Sensor PR-011-0900
This sensor element can measure a pulling force on a wire or string, or a pushing force via a ball. It can be encapsulated in a laser-cut metal enclosure for easy installation.
Centered Force Sensor KZ-011-0400
The shape of this sensor allows it to be mounted in a round drilled hole. It is available in several thicknesses and is a simple and affordable solution to measure a vertical force acting on a surface.
OEM Pressure Sensor
This sensor was developed for a specialized pressure sensing application.
