More than a decade of research in the field of thermal, motion, vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent(More)
Power autonomy is an important requirement for wireless sensor nodes. Thermoelectric generators can produce sufficient power for low power applications. Due to varying temperature, a power management circuit will be required. This paper presents such a power management circuit, realized in the AMIS I3T80 CMOS technology. It contains a Dickson charge pump(More)
Energy harvesters [1] power energy-autonomous wireless sensor systems by converting ambient environmental energy into electrical energy. Thermoelectric generators (TEG's) are a suitable compact power supply for both on-the-body and industrial sensors. Due to changing conditions, the generated power and voltage vary. Therefore a power management circuit(More)
Future wireless sensor nodes will, for certain applications, require only a few microwatts of energy. Micro-machined thermoelectric generators can produce such amount of electrical energy, but variations in the generated power and voltage make a power management circuit necessary to generate a suitable power supply for the sensor node. This paper compares 2(More)
More than a decade of research in the field of thermal, motion, and vibrational energy scavenging has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC-DC conversion are becoming able to efficiently convert the power from these energy scavengers. This paper summarizes recent energy scavenging results(More)
Energy scavenging is an emerging method to power energy-autonomous wireless sensor systems by converting ambient environmental energy into electrical energy. Miniature as well as micro-machined thermoelectric generators (TEG) can become a suitable compact power supply for both on-the-body and industrial sensors. To minimize the overall size of the power(More)
In today's world, there is a huge demand for portable electronic systems such as RFID cards, PDA, watches, calculators, cell phones, flash memories, MEMS, LCD drivers etc. The limited battery lifetime is the main concern of many portable systems. Energy harvesting system overcomes these problems by converting non-conventional energy into useful energy.(More)
This work concentrates the recently developing remote wireless powered communication network in which one hybrid access point (H-AP) with constant power supply coordinates the wireless energy/information transmissions to/from a set of distributed users that do not have other energy sources. A “harvest-thentransmit” procedure is planned where all client(More)
