This paper presents a new type diode connected MOS transistor to improve CMOS conventional rectifier's performance in RF energy harvester systems for wireless sensor networks in which the circuits are designed in 0.18  μm TSMC CMOS technology. The proposed diode connected MOS transistor uses a new bulk connection which leads to reduction in the threshold voltage and leakage current; therefore, ...

A prototype mobile chip harvester has been designed to harvest forest biomass in the form of 1 ogging residuals for use as energy wood. The prototype is presently undergoing developmental tests. Results are encou raging, indicating mechanical feasibility with prospects of working systems within the next several years. Papers presented before ASAE meetings are consldered to be the property ot th...

A new measurement concept for cut-to-length forest harvesters is presented in this paper. The cut-to-length method means that the trees are felled, delimbed and cut-to-length by the single-grip harvester before logs are transported to the roadside. The concept includes measurements done to standing trees before felling to calculate optimal length of logs. The modern forest harvesters use mechan...

• Novel self-tuning rotational vibration energy harvester concept for powertrains. The eliminates the use of protruding beams in harvester. Pendulum on tautochrone path resonance matching a frequency order. generated power drives an electronic circuit with temperature sensor. A physical prototype tested at lab validates proposed design. During conversion between mechanical and electrical within...

Radio waves carry both energy and information simultaneously. Nevertheless, Radio-Frequency (RF) transmission of these quantities have traditionally been treated separately. Currently, we are experiencing a paradigm shift in wireless network design, namely unifying wireless transmission of information and power so as to make the best use of the RF spectrum and radiations as well as the network ...
