Self-powered autonomous wireless sensor node
This paper reports the development and implementation of an energy aware autonomous wireless condition monitoring sensor system (ACMS) powered by ambient vibrations. An electromagnetic (EM) generator has been designed to harvest sufficient energy to power a radio-frequency (RF) linked accelerometer-based sensor system. The ACMS is energy aware and will adjust the measurement/transmit duty cycle...
متن کاملEnergy Harvesting for Self Powered Sensor Systems
Wireless autonomous sensor systems become steadily standard components in our environment and they become smaller, cheaper and more sophisticated. Energy harvesters fabricated by micro-system technology can realize the autonomy of those systems. An overview of latest results and remaining challenges will be given with the focus on vibration energy harvesters. These harvesters are of specific in...
متن کاملTowards an autonomous self-tuning vibration energy harvesting device for wireless sensor network applications
Future deployment of wireless sensor networks will ultimately require a self-sustainable local power source for each sensor, and vibration energy harvesting is a promising approach for such applications. A requirement for efficient vibration energy harvesting is to match the device and source frequencies. While techniques to tune the resonance frequency of an energy harvesting device have recen...
متن کاملEnergy Harvesting for Wireless Autonomous Sensor Systems
All these devices need a compact, low-cost and lightweight energy source, which allows the desired portability and energy autonomy. Today, batteries represent the dominant energy source for the devices listed in Table I and alike. In spite of the fact that energy density of batteries has increased by a factor of 3 over the past 15 years, their presence in many cases has a large impact on, or ev...
متن کاملEnergy-autonomous wireless sensor nodes for automotive applications, powered by thermoelectric energy harvesting
In this paper we will first present the measurement of temperatures on different positions at a diesel-powered car. As a result, several locations are identified as suitable to implement a wireless sensor node powered by thermal energy harvesting. Based on the data gained a thermoelectric generator (TEG) has been selected, and measurements of energy generation have been performed. Further, a co...
