Energy harvesting ASIC for autonomous sensors

2016 IEEE International Symposium on Circuits and Systems (ISCAS), 2016
In this paper, we present a blackout and brownout insensitive energy harvesting ASIC for ultra-low power autonomous sensor applications. It utilizes both RF or DC power inputs to deliver a regulated voltage for on-chip and off-chip devices. A voltage limiter has been integrated for overvoltage protection. As the ASIC utilizes two regulators alternately,

Autonomous wideband mechanical energy harvester

2012 IEEE International Symposium on Industrial Electronics, 2012
The aim of this work is to demonstrate, by theory and experiment, the feasibility of a mechanical energy harvester able to operate with a high efficiency over a wide vibration frequency band. Herein this work we propose a new method for adjusting the resonant frequency of a mechanical harvester, based on piezoelectric material.

Rice Autonomous Harvesting: Operation Framework

Journal of Field Robotics, 2017
This paper reports on an operation framework for autonomous rice harvesting. We developed an integrated algorithm for robotic operation and cooperation with farmworkers to automate each subsection of the harvesting and unloading process and of the processes that bridge them (homing and restarting).

Energy Harvesting for Autonomous Sensing

Key Engineering Materials, 2007
Autonomous, wireless structural health monitoring is one of the key goals of the damage monitoring industry. One of the main roadblocks to achieving autonomous sensing is removing all wiring to and from the sensor. Removing external connections requires that the sensor have its own power source in order to be able to broadcast/telemetry information ...

Energy Harvesting for Autonomous Wireless Sensor Networks

IEEE Solid-State Circuits Magazine, 2010
Wireless sensor nodes (WSNs) are employed today in many different application areas, ranging from health and lifestyle to automotive, smart building, predictive maintenance (e.g., of machines and infrastructure), and active RFID tags. Currently these devices have limited lifetimes, however, since they require significant operating power.

Smart autonomous grain carts for harvesting-on-demand

2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2017
In this work, we address the problem of centralized scheduling and motion planning for multiple grain carts with finite capacity that serve a group of combine harvesters engaged in a harvesting operation. First, we solve a facility location problem of finding the optimal depot position to minimize the distance traveled by the grain carts.

A Fully Autonomous Integrated Interface Circuit for Piezoelectric Harvesters

IEEE Journal of Solid-State Circuits, 2012
This paper presents a fully autonomous, adaptive pulsed synchronous charge extractor (PSCE) circuit optimized for piezoelectric harvesters (PEHs) which have a wide output voltage range 1.3-20 V. The PSCE chip fabricated in a 0.35 μm CMOS process is supplied exclusively by the buffer capacitor where the harvested energy is stored in.

Piezoelectric pressure harvester for autonomous sensors

Smart Structures and NDE for Energy Systems and Industry 4.0, 2019
Determining the exact location of people and objects is a big benefit in times of IoT. It can achieve a tailored surrounding for humans for example by controlling lights or air conditioning systems when needed thus saving energy. It can also help with a smoother navigation for example by pointing to available spaces for parking cars or storing goods ...
