MEMS Pressure Sensor Die for Catheters

Users looking for the smallest possible MEMS pressure sensor die for their medical catheter application can opt for NovaSensor’s range for the perfect fit. With products ranging in size, pressure range, and ease of integration, NovaSensor is sure to have the sensor solution you are looking for.

NovaSensor not only has in-house wafer fabrication, but also the manufacturing infrastructure and technical know-how to design, develop, test and modify sensors right within its own facilities. NovaSensor provides the smallest-ever catheter die solutions and capabilities in the industry along with superior performance.

The use of ultra-small MEMS pressure die presents ultra-small assembly and handling difficulties. Hence, NovaSensor provides evaluation kits and die that include wire sub-assemblies. This eliminates the manufacturing difficulty and makes it very simple to connect to the die, thereby offering the output signal in a standard usable form.

For customers who find it difficult to choose a die that precisely fits their application, NovaSensor offers the engineering expertise to design a custom die to meet their needs.
