“…Piezoelectric transducers are characterized by higher energy density (35.4 mJ cm −3 ) compared to electrostatic (4 mJ cm −3 ) and electromagnetic (24.8 mJ cm −3 ) transducers. [63] The piezoelectric transducers benefit from their smart piezoelectric materials with inherent transduction capacity, while the other transducers require additional conditions to generate electricity, such as external source (electrostatic transducers), induction magnetic field (electromagnetic harvesters), and frictional contact (triboelectric generators). [64] Furthermore, piezoelectric materials can generate the opposite electric charges in response to the mechanical strain, known as the piezoelectric effect.…”

Cardiovascular disease continues to be one of the dominant causes of global mortality. One effective treatment is to utilize cardiovascular implantable devices (cIMDs) with multi‐functional cell sensing and monitoring features that have the potential to manipulate cardiovascular hyperplasia disorders as well as provide therapy. However, batteries with a fixed capacity entail high‐risk surgeries for battery‐replacement, which causes health hazards and imposes significant costs to patients. This review accesses comprehensive power solutions for cIMDs, from conventional batteries to state‐of‐the‐art energy harvesters and wireless power transfer (WPT) schemes. In particular, WPT has great potential to eliminate the percutaneous wires and overcome frequent battery removal. Here, the fundamentals, power transfer efficiency, antenna design and miniaturization, and operating frequencies in various WPT schemes are presented. Moreover, the power loss attenuation and bio‐safety standard (specific absorption rate) for implants are also considered in WPT design envelope. In addition, wireless data transmission of implantable devices from external to internal milieu (and vice versa) along with different modulation and demodulation techniques are investigated. The last advanced power solutions for cIMDs in in‐vivo and in vitro research are illustrated throughout. Finally, specifications and future potential of WPT systems in cIMDs are highlighted.

Internet of Things (IoT) has been developing to become a free exchange of useful information between multiple real-world devices. Already spread all over the world in the most varied forms and applications, IoT devices need to overcome a series of challenges to respond to the new requirements and demands. The main focus of this manuscript is to establish good practices for the design of IoT devices (i.e., smart devices) with a focus on two main design challenges: power and connectivity. It groups IoT devices in passive, semi-passive, and active, giving details on multiple research topics. Backscatter communication, Wireless Power Transfer (WPT), Energy Harvesting (EH), chipless devices, Simultaneous Wireless Information and Power Transfer (SWIPT), and Wake-Up Radio (WUR) are some examples of the technologies that will be explored in this work.

“…The research motivation in this field is due to the reduced power requirement of small electronic components, such as the wireless sensor networks used in passive and active monitoring applications [2]. The harvesters based on energy can be categorized into three types, namely electromagnetic, piezoelectric, and electrostatic, depending on the medium of the transducer [3]. In this work, the electromagnetic energy harvester device, mounted in the suspension of the pendulum is proposed.…”

This paper presents harvesting energy analysis of an autoparametric system consist of a pendulum suspended on a Duffing oscillator. This construction is often used for dynamic vibration absorption effect or energy harvesting. The work proposes conception of simultaneous elimination of vibration and energy induction by a pendulum motion. The energy recovery based on a linear induction of a rotatory device mounted in pendulum pivot.
