MSI
Sensors Acquires Elekon Industries
Gains New Optical Sensing Technology Capabilities
This
past summer, MSI Sensors acquired three companies to rapidly increase
capabilities and product offerings for our customers: Encoder Devices,
Elekon Industries and Entran. Encoder Devices and Entran were profiled
in previous
issues.
Elekon
designs and manufactures optical sensors and components sold primarily
to the medical and security markets. Their products include pulse oximetry
(SpO2) sensors for use in hospitals and other primary and secondary care
environments. These non-invasive sensors are used to measure blood oxygen
saturation and pulse rate. Elekon customers include medical device manufacturers
such as Tyco, Phillips and GE. The Elekon SpO2 sensors are offered in
disposable versions for use with an OEM device and in a reusable format.
Elekon
also designs and manufactures optical electronics components such
as infrared detectors assemblies (Si based), light sources with various
wavelength combinations (LEDs) and photodiodes. Elekon has a strategic
relationship with India-based Opto Circuits India, Ltd., who assembles
most of the division’s products.
In
September, Elekon received FDA clearance to start marketing and selling
sensors made with its
patent-pending Flexistat™ technology. Flexistat™ is
a multi-platform delivery system which enhances durability and accuracy
of the SpO2 sensors while reducing manufacturing costs. "Obtaining
FDA approval for our new line of OEM sensors enhances our position
as a market leader and innovator in medical sensing,” noted Thomas
Dietiker, founder of Elekon and now product line manager of optical
products for
MSI Sensors.

Vibration
Sensing Expert Joins MSI Sensors
MSI
Sensors is pleased to announce that Anthony Chu has joined the
company as Director, Vibration Sensors Business Unit. He will lead
MSI Sensors’ global initiative to significantly expand its
accelerometer and vibration sensing business with customers in
the automotive, medical, military/aerospace and consumer goods
industries.
Mr.
Chu has 25 years of engineering and marketing experience in the
sensor industry
with a special emphasis on piezoelectric and
piezoresistive sensor designs and MEMs development. He is an internationally
known authority and published author on the subjects of shock measurement
and accelerometers. Mr. Chu is fluent in Chinese, which will facilitate
his work with MSI Sensors’ engineering and manufacturing center
in Shenzhen, China.
For more than two decades, Mr. Chu worked at Endevco Corporation,
a division of Meggitt PLC, in roles of increasing responsibility.
Most recently, as Director of Product Management, he managed the
entire Endevco product line of piezoelectric, silicon MEMs and electronic
systems products. Mr. Chu also held leadership positions in marketing,
manufacturing and engineering design.
“We are thrilled to bring on a talent such as Anthony Chu
to further develop our growing portfolio of vibration sensing technologies,” noted
Vic Chatigny, Vice President and General Manager of MSI Sensors. “Mr.
Chu will build on the platform we’ve established with our capabilities
in silicon MEMs, piezoelectric polymer film, piezoelectric ceramic,
bonded gage and accelerometer miniaturization through our recent
Entran acquisition.”
Mr. Chu commented: “I see great opportunity for MSI Sensors
in vibration sensing because of the company’s uniquely broad
technology portfolio. Our expanded toolbox provides competitive advantage
because we can choose the best possible way to solve customer problems
and achieve high performance at very competitive costs.”

MSI
Sensors Receives Patents for Piezo Film Inventions
| MSI
Sensors recently received two US patents for piezo film-based transducer
elements and housing. The inventor was Dr.
Minoru Toda, senior research
scientist with MSI Sensors’ piezo film engineering center.
These ultrasonic transducers are used to create pen and whiteboard
digitizers that transfer writing on a tablet to a computer,
mobile phone display, projector or to digital files. Three
high frequency ultrasonic sensing elements – two receivers
on the tablet and one transmitter on the pen – are fashioned
out of piezo film. The housing magnifies the amplitude of the
transmit signal and protects the sensor element. MSI Sensors
offers this technology to consumer electronics OEMs.

Piezoelectric fluoropolymer film, or piezo
film for short, is an enabling sensor technology with
unique capabilities. Like conventional piezoceramic
materials, piezo films produce voltage in proportional response
to compressive or tensile mechanical stress or strain,
making it an ideal dynamic strain gage. It makes a
highly
reliable vibration sensor, accelerometer and switch
element. Conversely, Piezo film undergoes a proportional change
in dimension under the influence of an applied electric
field at frequencies from DC to 100 MHz. This property,
as well as the film’s low impedance, makes piezo
film ideally suited for high fidelity transducers operating
throughout the high audio (>1KHz) and ultrasonic
(up to 100MHz) ranges.
