Special Issue Information

 Dear Colleagues,

Wearable and implantable electronics are emerging technologies with widespread applications in portable computing/communication systems, healthcare, medicines, etc.; however, their progress has been limited by energy supply due to the limited lifespans of batteries or the need for a wire connection for electricity. Energy harvesting is a promising technology, which can solve the energy problem for wearable and implantable electronics in the future. Wearable electronics can either use the power harvested from the ambient environment to replenish its batteries, or be designed as self-powered devices without batteries. The energy could be harvested from various sources, such as solar power, electromagnetic wave, thermal energy of body, and mechanical vibration induced during walking, body motion, by heartbeats, etc., based on photoelectric, piezoelectric, pyroelectric and triboelectric effects, etc. The purpose of this Special Issue is to gather the latest developments in energy harvesting technologies and applications in wearable electronics. We welcome all manuscripts with novel ideals in device principles and structures, development and applications of energy harvesting technology with, but not limited to, the following topics: 

  • Novel energy harvesting principles and device structure designs
  • Energy harvesting for powering batteries in wearable/implantable electronics
  • Wearable electronics with self-powered designs without batteries
  • Methods and tools to theoretically simulate and characterize the performance of energy-harvesting devices and applications
  • Development of energy storage unit, such as supercapacitors, in wearable electronics
  • Power management design of energy-harvesting system for a better energy conversion efficiency for wearable electronics

This paper proposes a new Unified Switch Fault Diagnosis (UFD) approach for two-stage non-isolated DC-DC converters used in energy harvesting applications. The proposed UFD is compared with a switch fault diagnosis consisting of two separate fault detection algorithms, working in parallel for each converter. The proposed UFD is simpler than the two parallel fault diagnosis methods in realization. Moreover, it can detect both types of switch failures, open circuit and short circuit switch faults. It can also be used for any two-stage non-isolated DC-DC converters based on two single switch converters, no matter the converter circuits in each stage. Some selected simulation and Hardware-in-the-Loop (HIL) experimentation results confirm the validity and efficiency of the proposed UFD. Also, the proposed UFD is applied successfully for fault-tolerant operation of a buck/buck–boost two-stage converter with synchronous control and a redundant switch. Full article

A dual-output voltage reference circuit with two reference voltages of 281 mV (Vref1) and 320.5 mV (Vref2) is presented in this paper. With a novel and precise circuit structure, the proposed circuit, operating in the subthreshold region, integrates two different output voltages into a circuit to form a dual-output voltage reference, and cascode current mirrors are used to enhance the power supply rejection ratio (PSRR). The proposed circuit was designed in a standard 0.18-µm CMOS process and has a series of attractive features: low-temperature coefficient (TC), high-PSRR, low-Line sensitivity (LS), small-chip area and low-power consumption. Monte Carlo simulations for 2000 samples showed that the output voltages 281 mV and 320.5 mV had a variation coefficient of 1.73% and 1.44%, respectively. The minimum power consumption was 84.1 nW at 0.9 V supply, proving that the circuit is suitable for portable biomedical application. The active area of the proposed voltage reference was only 0.0086 mm2. Full article

In this research work, we investigated a dual switch (DS) active rectifier for the piezoelectric (PE) energy scavenging system. In the proposed DS active rectifier configuration, two extra switches are shunted across the PE transducer which helps the PE transducer’s capacitor in charging and discharging which results in maximum power extraction from the PE transducer. Moreover, in the proposed rectifier configuration comparator controlled active diodes are used instead of conventional/passive diodes to minimize the threshold voltage V T H drop. The proposed DS active rectifier design is fabricated in a 1-poly 6-metal 180-nm standard CMOS process. The simulation and measured results of the proposed DS active rectifier design have the better power conversion efficiency (PCE) of 91.5 %, which definitely helps in extracting more power than the conventional full bridge rectifier (FBR).

The increasing world human population has given rise to the current energy crisis and impending global warming. To meet the international environmental obligations, alternative technological advances have been made to harvest clean and renewable energy. The solar photovoltaics (PV) system is a relatively new concept of clean technology that can be employed as an autonomous power source for a range of off-grid applications. In this study, the dual battery storage system is coupled with a solar PV system and a low voltage grid, benefitting from the feed-in tariff (FIT) policy. The main outcomes of this study are: (I) A novel dual battery storage system for the optimal use of the PV system/energy is proposed; (II) The problem is formulated in the form of a mathematical model, and a cost function is devised for effective cost calculation; (III) An optimal cost analysis is presented for the effective use of PV energy; (IV) real-time data of a solar PV taken from the owner and the demand profile collected from the user is applied to the proposed approach, with United Kingdom (UK) tariff incentives. This system works in a loop by charging one system from the solar PV for one day, and discharging the other system. This model gives certainty that power is exported to the grid when the solar PV generates an excess amount; batteries are utilized during the peak hours, and power is purchased when the demand is not met by the batteries, or when the demand is higher than the generation. This study examined the economic knowledge of solar PV and battery storage systems by considering the FIT incentives. Full article

As worldwide awareness about global climate change spreads, green electronics are becoming increasingly popular as an alternative to diminish pollution. Thus, nowadays energy efficiency is a paramount characteristic in electronics systems to obtain such a goal. Harvesting wasted energy from human activities and world physical phenomena is an alternative to deal with the aforementioned problem. Energy harvesters constitute a feasible solution to harvesting part of the energy being spared. The present research work provides the tools for characterizing, designing and implementing such devices in electronic systems through their equivalent structural models. Full article
