Market Analysis

MEMS

  • MEMS is expected to grow from $8 billion in sales in 2010 to $16.4 billion by 2015, according to Yole Développement, a market research firm based in Lyon, France. The forecast reflects a compound annual growth rate (CAGR) of about 15 percent.
  • iSuppli Corp., a market research firm based in El Segundo, Calif., forecasts MEMS device sales to climb from more than $6 billion in 2010 to about $10 billion in 2014, representing a CAGR of 11.6 percent. And it’s possible that growth rate could continue through 2020, bringing the MEMS market to more than $20 billion.Source
  • One difference in the two forecasts is emerging MEMS markets in borderline device like electronic-compasses, which Yole counts but iSuppli does not include. Also, iSuppli only counts microfluidic devices cast on silicon substrates, whereas Yole includes microfluidics on polymer and glass substrates. Source

  • Major changes such as an aging population and growing obesity issues in many countries (leading for example to diabetes or other disorders) are impacting the medical MEMS market. These and other factors are among the motivations for making treatments less invasive or for monitoring the movements of the elderly. MEMS used in insulin pumps increase the efficacy and comfort of insulin drug delivery, for instance, while accelerometers monitor elderly people, tirelessly watching their movements, their position or presence in a bed, if they fall, and so on.
  • Pressure sensors monitor gases during surgical operations or the treatment of sleep apnea. Accelerometers and gyroscopes assist surgeons by removing shake during precise operations. Emerging applications include implantable wireless pressure sensors, which are showing great promise in monitoring tell tale pressure buildup following heart surgery and are used for post-op monitoring of aneurisms. As a result markets for medical diagnostics and drug delivery devices enjoy 34% and 32% CAGR respectively from 2009 to 2014. Source
  • The global market for MEMS used in medical applications is forecasted to reach $430 million by 2014, up from $229 million in 2009, equating to a CAGR of 13 percent, as shown in the figure.
