Living life under 1uW - Extreme Deeply Embedded Computing
Mark Buccini, Director, Texas Instruments

In the world of energy harvesting, wireless sensor system and implantable medical devices, available power is pushed to the absolute minimum, but at the same time, require some level of real-time computing. Is it possible to compute under 1uW? With careful hardware and firmware design, the answer is a remarkable yes! This presentation will outline common and often over-looked practices as well as completely unique techniques that can be utilized today using off-the-shelf microcontrollers (MCU) that achieve real-world, deeply embedded computing under 1uW. 

To achieve the absolute lowest possible power consumption, the smartest system-level design is in order and include; hardware set-up, power-wise firmware design, minimized active time, peripheral feature usage and the most efficient sensor measurement are required. Understanding exactly just where power is consumed, how to minimize it and avoiding the most common traps are discussed. A live and interactive demonstration will be made using the techniques discussed.


2:30 PM – 3:10 PM
Integration of Thin-Film Thermoelectrics in New Energy Harvesting Sensor Applications
Bob Collins, VP of Business Development, Nextreme

Advances in distributed sensors and sensor networks have led to an increased interest in the use of renewable power sources to replace or augment existing power systems. The use of heat is an attractive source of energy for many low-power sensor applications.
● Hear how microscale thin-film thermoelectrics are creating new applications and markets for energy harvesting, ranging from motion sensors in buildings and integrated bearing condition monitoring in turbine engines to data acquisition in plumbing and hands-free faucets.
