In medical technology, the reliability and stability of sensor measurements is extremely important. For example, an infusion pump must reliably detect when the infusion flow is blocked. Thin-film technology has a particular advantage here, as it allows sensors to be applied directly to metal parts without creeping layers. Below is a list of some OEM applications that have been realized with Senstech thin-film strain gauges.
Pressure Surveillance in Infusion Pumps
In infusion pumps from Arcomed and another well-known manufacturer, our sensors monitor the pressure in the infusion tube. Thus, kinks in the tube or complications at the puncture site are detected and trigger an alarm on the device.
Sensor for Infusion Pumps
Here you can see the installation situation of the sensor that monitors the pressure in Arcomed peristaltic pumps. In the event of excess pressure in the hose, the tongue of the sensor is deflected via a bolt. The amplified signal is transmitted to the control unit and evaluated there.
Manipulation Aid in Insulin Pumps
Senstech supplies an established manufacturer of insulin pumps for diabetes patients with miniaturized sensors. They measure the contact pressure of the plunger and serve as manipulation aids when changing ampoules.
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 Surveillance in Phaco Systems
A more recent application is the measurement of irrigation fluid pressure in phacoemulsification systems for ophthalmic surgery. Also in this area, Senstech supplies two well-known device manufacturers with OEM sensors. (Symbol image, © CBM/Fundación Visión)
Hardness Measurement for Cardiotocography
A manufacturer of labor detectors (tocodynamometers) has been relying on sensors from Senstech for several product generations. They are used as measuring elements to monitor the contractions during childbirth.

This sensor belongs to our standard range of force sensors and is installed in tocodynamometers with a customer-specific plastic housing.
Swiss Quality and Know-How
Senstech has many years of experience in the development and production of sensors. Some of our products for medical technology have been in production for over 20 years. All production steps from raw sheet metal to the finished sensor are carried out at our premises in Switzerland. As an ISO 9001 and ISO 13485 certified company, we are familiar with the regulatory framework of the industry.
