ES2: Wireless sensor systems: Solution & technology

Abstract

Recently, we start to see Wireless Sensor Network (WSN) solutions on the market, which are mostly based on 802.15.4 standard or Zigbee equivalent. Most of these solutions integrate an 8-bit to 32-bit low power microcontroller, one or multiple sensors and run on batteries. However, business is not yet there massively. Does it mean we need additional innovation to boost market adoption? The aim of this session is to provide the ISSCC audience comprehensive and innovative information. It will allow discussion to understand what new techniques are required for the next generation of wireless sensor systems. This Special Evening Topic session will present current wireless sensor system solutions, and explore what could be the next innovations to come. We will review what changes could be operated at designer level, and which low power design techniques will allow the system to run the extra mile in terms of energy efficiency. MEMS are at the heart of the wireless sensor system, and its integration must be realized at the lowest cost. For this purpose, some heterogeneous techniques for industrial sensors integration on CMOS substrate will be presented. Realization of autonomous Wireless Sensor Networks seems to be a trend with first announcements at industry level. Next generation energy storage techniques will be discussed to enable longer autonomy and easier integration into Wireless Sensor Systems. Finally, we will consider innovative solutions for energy scavenging from light, temperature, vibration or even radiofrequency and their power level compatibility with wireless systems.
