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.
