چکیده
Recent advances in ultra-low power chip design techniques, many originally targeting wireless sensor networks, will enable a new generation of body-worn devices for health monitoring. We utilize the state-of-the-art in low power RF transmitters, low voltage boost circuits, subthreshold processing, biosignal front-ends, dynamic power management, and energy harvesting to realize an integrated reconfigurable wireless body-area-sensor node (BASN) SoC capable of autonomous power management for battery-free operation.

متن کاملA New Approach to Design Autonomous Wireless Sensor Node Based on RF Energy Harvesting System
Energy Harvesting techniques are increasingly seen as the solution for freeing the wireless sensor nodes from their battery dependency. However, it remains evident that network performance features, such as network size, packet length, and duty cycle, are influenced by the sum of recovered energy. This paper proposes a new approach to defining the specifications of a stand-alone wireless node b...
متن کاملDistributed Energy Harvesting Emulation
Motivation In traditional energy harvesting applications, sensor nodes are able to store any excess energy in a storage device such as battery or supercapacitor for future use. If correctly dimensioned, such a system will guarantee the node’s operation during periods of energy unavailability. More recently, a radically different research line has emerged which focuses on batteryless, energy-dri...
