AdapTIvEnergy wireless sensing solution with Texas Instruments ultra-low power technology makes energy harvesting a reality
AdapTIvEnergy launched a demo kit developed with Joule-Thief technology for energy harvesting, and for Texas Instruments (TI) ultra-low power MSP430 microcontroller (MCU) and RF technology to collect data, control system operation or will sense The measured data is transmitted to the central collection station to provide the core power. The kit fully demonstrates the superiority of energy harvesting and radio frequency (RF) technology in wireless sensing, monitoring, or environmental intelligence. The Joule-Thief energy harvester is based on the Ruggedized Laminated Piezo (RLP) technology of AdaptiVEnergy. This technology enables compact energy harvesting modules to provide core power for applications such as wireless sensors. These wireless sensors can be used to collect environmental intelligence information wirelessly or without batteries, to detect and report hazardous conditions in factories, automobiles, office buildings, homes, and other environments.Emerging markets with great potential
According to the statistics of the Darnell Group, the global market for energy harvesting solutions for wireless sensor systems has great potential. It is expected that the size of this market will reach about 164 million units by 2013, with a compound annual growth rate of nearly 65%. Energy harvesting is an important emerging field of low-power technology, which can not only meet large-scale energy needs through wind and solar systems, but also meet small-scale needs such as sensor networks. The technology makes full use of the inherent vibrations in buildings, vehicles, and machinery to generate or collect energy, so that sensors can be driven wirelessly and without batteries. For example, with the help of Joule-Thief technology, sensors can collect energy from the rumbling vibrations generated by vehicles on the bridge, and then transmit the data from all wireless sensors on the bridge to the collection point, so that the data can be analyzed at the collection point. To monitor the structural soundness of the bridge structure.
Energy harvesting becomes cheap and simple
In the past, powering the sensor-transmitter network system required huge investments in wiring or regular battery replacement. However, it may not be feasible to use wired sensors to collect data in hard-to-reach or dangerous areas, or even cause personal injury or death during circuit installation and battery replacement. Nowadays, AdaptivEnergy's Joule-Thief technology not only makes remote structure and safety monitoring easy, but also significantly reduces the cost of related procedures.
Joule-Thief technology perfectly combines AdaptivEnergy's unique stress-biased RLP energy harvesting beam, which converts vibration or motion into usable electrical energy. Compared with piezoelectric energy harvesting devices, RLP Smart Energy Beam (RLP Smart Energy Beam) allows more than ten times the stress on the piezoelectric ceramics, thereby generating more conversion power for the system. In addition to directly sensing motion, this versatile design can accept input from external sensing components, helping to detect stress in bridges and high-rise buildings, the degree of loss of factory equipment, automobiles, and many other environmental conditions Overheating, hazardous chemicals, and unsafe conditions.
The working intelligence and communication based on the chipset composed of the MSP430F2274 microcontroller and CC2500 RF transceiver form a beneficial supplement to the RLP smart energy beam and electronic collection equipment, so that the Joule-Thief design can be extracted from the charge stored in the capacitor Get as much processing and transmission as possible. The MSP430 microcontroller has industry-leading ultra-low power consumption characteristics in working and standby modes, enabling quick wake-up of less than 1 microsecond for better low-power / high-performance solutions.
System-on-chip (SoC) integration with MSP430 microcontroller peripherals such as analog-to-digital converters (ADCs), timers, comparators, and various memory configurations not only helps AdaptivEnergy save space and reduce board costs, but also So that it can build maintenance-free wireless sensors suitable for various environmental intelligent applications. TI's CC2500RF transceiver operates in the 2.4GHz range, making it suitable for reliable, low-cost digital wireless applications.
Work quickly with the Joule-Thief demo kit and eZ430-RF2055 development tools
The Joule-Thief Energy Harvesting Demonstration Kit provided by AdaptivEnergy includes a matchbox-sized RLP smart energy beam and collection and storage electronics, making it easy for developers to study energy harvesting from vibration. In addition, AdaptivEnergy also provides TI's eZ430-RF2500 microcontroller development tool, which includes all the hardware and software required to develop a complete wireless control network and an emulator for in-system programming and debugging provided in the form of a USB stick. By using the Joule-Thief kit in combination with the eZ430-RF2500 microcontroller tool, developers can have a complete set of low-cost, low-power wireless sensor systems designed to be driven by environmental vibrations.
AdaptivEnergy has reached cooperation agreements with many industry-leading system developers currently using Joule-Thief design to jointly develop advanced sensing applications that will be available in the next one to two years. In addition, AdaptivEnergy has also reached a strategic agreement with In-Q-Tel, which is responsible for discovering innovative technologies for the US intelligence community.
Reverse Conducting Thyristor(RCT) is also called Reverse- appreciation Thyristor.The characteristic is that a diode is connected in reverse parallel between the anode and cathode of thyristor, so that the transmitting junction of anode and cathode is short-circuited.As a result of this special circuit structure, it has high voltage resistance, high temperature resistance, short turn-off time, low switching voltage and other good performance.For example, the turn-off time of the reverse thyristor is only a few microseconds, and the working frequency is dozens of KHZ, which is better than the fast thyristor (FSCR).This device is suitable for switching power supply and UPS uninterrupted power supply. One RCT can replace one thyristor and one continuous current diode respectively.
