Scavenging energy from readily available sources offers the potential to power applications indefinitely without wires or batteries, or at minimum extend the operating times of battery-powered systems. However, successfully implementing a vibration energy harvesting solution requires detailed understanding of the vibration source characteristics and harvester / transducer output power capabilities as well as a detailed understanding of the system power needs. This presentation will describe characteristics of piezoelectric and electromagnetic induction generators and provide methods for characterizing a vibration source for peak acceleration and frequency modes. Generator open circuit voltage, maximum power point tracking, and charge storage methods for optimizing available system power will be discussed. Startup and quiescent power saving strategies will be provided using readily available piezoelectric generators and integrated circuits.
Continued advancements in the combined fields of micro-energy storage and energy harvesting have driven the development of a new integrated energy management solution for self-powered wireless nodes utilizing various methods of energy harvesting to provide continuous, maintenance-free operation. A new power management integrated circuit (PMIC) is being introduced that combines all of the critical elements for effective, low cost, practical energy harvesting and storage. Considerations that have been addressed by the PMIC include:
- Battery management, including under-voltage and over-voltage protection, along with high efficiency charge management suitable for ultra-low power charge sources producing less than 1µA.
- Multiple output voltage regulation levels that are required to obtain the most efficient usage of the various low power microcontrollers and radio sets currently available for wireless nodes.
- An extremely low quiescent current output regulator that requires less than 75nA of quiescent current to supply a regulated output, needed for the ultra-low power microcontroller sleep states and real time clocks that are being produced by major IC manufacturers, currently advertised to be well below 100nA.
- Input boost conversion that allows input sources down to 200mV to be boosted to levels suitable for charging a micro-battery, such as a THINERGY® Micro-Energy Cell (MEC), and operates only when input charge energy is available, eliminating unnecessary quiescent power normally required to maintain a functioning boost charging circuit.
- Built-in "off-active" operation that allows nodes to operate only when input events meet activation criteria, resulting in a power management solution that requires less than 1nA of quiescent current.
- Support for cold temperature operation utilizing an external capacitor to boost cold temperature output power performance which is often a limiting factor for battery powered systems.
All considerations above will be discussed in detail.

Cost effective thermoelectric solutions for harvesting energy from small temperature differences require the integration and optimization of a number of thermal and electrical characteristics. For practical thermoelectric energy harvesting applications, small natural convection heat sinks are desired to maximize the available net power, minimize size, reduce cost and maximize system reliability. Thermal matching of the thermoelectric generator to the heat sink is essential for achieving maximum power output from the thermoelectric device. Numerous thermoelectric designs, each with different number TE element dimensions and number of thermocouples can meet the thermal matching criteria. The latest low threshold voltage step-up circuits enable the use of small, cost effective, low couple count thermoelectric devices which can be matched electrically enabling operation with small temperature differences.

Wireless Sensor Networks (09:00 - 10:40)
09:00 - 09:25 "The Top Five Factors to Consider when Implementing a Wireless Sensor Network"As the proliferation of wireless technology continues, end users are encountering more and more choices for the implementation of their wireless systems. Emerging hardware vendors, new deployment and development techniques, and a clouded landscape of wireless protocols sometimes make migrating to a wireless solution seem like more trouble than it's worth. However, the benefits of a wireless solution are undeniable: lower installation and maintenance costs, increased flexibility, a broader set of addressable applications, and the freedom to take measurements almost anywhere. In this presentation, we make it easier to implement a wireless sensor network (WSN) system by taking a look at the top five factors to consider when implementing a WSN for your application.
