Microsystem Technology Adds Significant Value To The Measurement of
|Industrial sector (PRODCOM code)

Speidel & Keller GmbH in Jungingen, Germany, is a medium-sized
company with 44 full time employees and about 36 homeworkers. It has a
long tradition in manufacturing of me-cha-nical hand held aneroid sphygmomanometers.
These devices are used for the measurement of blood pressure. The company
has been specialised to the manufacturing of high-precision products which
are mainly used by the physicians and in the clinical area.
Here, Speidel & Keller is the market leader. In 1996 the company had a
turnover of about 11 M€.
However, the competitive pressure increases more and more. Manufacturers
from Far East and importers of digital and mechanical sphygmomanometers
who buy these devices are dominating the private consumer market. But
now they penetrate also more and more the professional clinic and physician
market -our main business area- constituting a real threat. Currently,
Speidel & Keller is the last European company which manufactures the movement
for the sphygmomanometer completely itself.
The rationale for doing the Application Experiment was to improve the
funtionality of our products in order to strengthen the market position
in the professional area and - if possible- to reduce the costs. This
was only feasible by substituting the existing mechanical solution by
an electronic one which combines a silicon membrane pressure sensor integrated
with passive electronics with a microprocessor for intelligent data processing,
i.e. a microsystem. The product to be improved in this way is a pressure
manometer with a fine mechanical movement which drives a pointer. The
pointer shows the actual pressure on a round dial (analogue display),
divided in small scales dependent upon the pressure range and required
accuracy (which can vary). The manometer can be used in any industry where
pressure has to be measured. However, the main application area will remain
the medical sector.
Because Speidel&Keller had only experiences in mechanical and microelectronic
designs based on discrete analogue and digital components, the necessary
management and development know-how in the area of microsystem technology
was transferred within the project.
However, we had to learn, that we could not achieve both: a cost reduction
and a higher functionality. Finally, we decided for the higher functionality
being the key for our competitive position. The costs for new solution
will be about 6 € compared with 3,50 € of the existing product. The possibility
to add additional features like data acquisition, data transmission or
automatic controlled pressure reduction improves the system in orders
of magnitude and allows a wider application range in comparable industrial
or consumer fields.
The Application Experiment was successfully finished with a working prototype
of the microsystem which was implemented into our conventional measurement
system. For the substitution of mechanical instruments in medical applications
a new battery powered system has been developed. It can be used now as
a stand alone system or as a measurement module in a complex system. This
development was based on the MCM technology.
The project ran for 16 months. The costs up to the working prototype were
about 288k€.of which 153K€ was the FUSE investment and 135K€ Industrialisation
costs. With the improved sales and profit a payback period of about 20
months and a ROI of about 250% are envisaged over a five year's life time
of the product.
