One of the MSS Alliance foundation members, NanoWorld AG has commercialized non-coated MSS chips "SD-MSS series" and an 8 Channel Readout Module "MSS-8RM", both for R&D on various sensing systems including olfactory/odor/gas applications. These products are available for the public through the NANOSENSORS™ channel.

The MSS is a sensor device developed by an international joint research group led by Genki Yoshikawa (International Center for Materials Nanoarchitectonics (MANA), NIMS) in 2011. NanoWorld AG has developed the "SD-MSS series" sensor chip with own MEMS know-how and technologies. Under the license from NIMS, these devices are commercially available to promote the MSS technology.

SD-MSS series: 1 sensor-per-chip, non-coated MSS


  • 1 sensor membrane per chip
  • Membrane diameter 1000 μm
  • Membrane thickness 5.2 μm or 2.5 μm
  • Various choice of receptor material (organic, inorganic, etc.)
  • High sensitivity (ppm ~ ppb)
    (*Strongly depends on the receptor material, sample gas to measure, measurement conditions.)
  • Small chip size (typ. 5.5 mm × 2.5 mm × 0.3 mm)
  • Fast response (~ a few seconds)
    (*Strongly depends on the receptor material, sample gas to measure, measurement conditions.)
  • Thermally, electrically, mechanically stable
  • Low power consumption (< 1 mW/ch.)

(Note: The available MSS chips are all in a bare condition (i.e., non-coated) when they are purchased . For olfactory/odor/gas sensing applications, an appropriate receptor material must be coated on the membrane by users. This product has different specifications than those used in the MSS forum.)

MSS-8RM: 8 Channel Readout Module

MSS-8RM is a basic electronic module to operate and to readout the SD-MSS series chip, up to 8 sensors simultaneously, in a hardware configuration for electronic nose/odor sensing. MSS-8RM contains two air pumps and users can examine self-prepared MSS under different gas flow conditions. MSS-8RM is designed as simply as possible so that users can learn about a basic electronic-nose system and further improve the system performance.


  • microcontroller, software
  • Two air pumps integrated
  • Two discrete sensors (Sensirion SHT21, Bosch BME280) integrated to monitor temperature and humidity
  • Compact and simple design

(Note: MSS-8RM is not an olfactory/odor/gas sensing system. This product does not include any data processing functions to distinguish one sample from the other. You will get raw numerical data of the sensor responses under different conditions as final output. This product has different specifications than those of the standard module used in the MSS forum.)
