Description First product of AMS in their new gas sensor activity after the acquisition of AppliedSensor.
Still focused on industrial and building applications with low volume, the gas sensor begins to penetrate the consumer market. It is a change in the market and volume.
It is to enter this growing market that AMS bought AppliedSensor in July 2014. Winning strategy with the integration of the first sensor for the Consumer in a home monitor from Withings.
The AV-MLV-P2 is a volatile organic compounds gas sensor which can detect alcohols, aldehydes, ketones, organic acids, amines, aliphatic and aromatic hydrocarbons.
With a very small footprint, less than to 3mm², the die sensor of the AV-MLV-P2 is well adapted to consumer applications.
Coming from industry, the technologies of AMS/AplliedSensor are reliable, robust, accurate and mature. The die is based on a Metal Oxide sensitive layer made on a micro hotplate. This allows a low power consumption: 34mW in continuous operation.
The experience of AppliedSensor in specific nitride layers explains the very thin membrane. A platinum heater and an electrode structure complete the micro hotplate.
The report provides all details on the structure of the component and the supply chain to produce this MEMS sensor. The report includes a detailed technology and cost analysis describing the innovations of AMS AplliedSensor.

SYSTEM PLUS CONSULTING
Across the Enterprise, from marketing to purchasing and R&D, product manufacturing cost is a major factor which has to be measured and then optimized. Since 1993, System Plus Consulting’s mission has been to develop and sell the right tools and services to meet these costing requirements.
System Plus Consulting utilizes an engineering approach to cost. Cost models and technology expertise are combined to provide customers with an accurate and objective estimation of manufacturing costs and selling prices.
Headquartered in Nantes, France, System Plus Consulting is specialized in technology and cost analysis of electronic components and systems. During our 20 years in business, we have built and refined detailed cost models as the primary tools for hundreds of analyses. The highly qualified System Plus cost engineers combine broad and deep skills in semiconductor and electronics technologies with years of experience in cost modeling.
− Custom reverse costing analyses: technology analysis followed by cost evaluation
− Standard reverse costing reports: regular publications on innovative products (available from our catalogue)
− Costing tools: software tools combining models and data to perform cost analysis
System Plus Consulting analyzes any type of electronic devices and systems, with a special focus on semiconductor technologies. Major fields of technology and cost expertise are:
