“…7). Once the capsule is placed in the docking station, the embedded battery is charged by the same method used for a mobile phone battery [19], i.e., based on electromagnetic induction. The proposed recharging system must be able to satisfy the recharge requirements of battery charging, in terms of recharge voltage (4.2 V) and recharging current (25 mA).…”

This paper aims to contribute to the advancement of the Wireless Capsule Endoscopy (WCE) field for ColoRectal Cancer (CRC) screening, by developing all electronic circuits to build an innovative wireless endoscopic capsule with a spherical shape, conceived to reduce the friction during its locomotion and thus improving patient's acceptability. The proposed capsule embeds an image sensor with optics and Light Emitting Diodes (LEDs), a control unit with a telemetry module, an actuation system, a battery with a smart recharging circuit able to recharge in 20 minutes, a smart power-on circuit and a localization module. Everything is devised to fit in a small spherical shape with a diameter of 26 mm and a weight of 12.70 g. The authors present a description of the sub-modules involved in the capsule development, together with the firmware and hardware integration. In order to reduce the bandwidth for matching the specifications of the target commercial telemetry, the firmware interfacing of a custom encoder was performed, which is able to compress the incoming images with a negligible loss of information and occupying a number of Look Up-Tables (LUTs) less than 1780. As a preliminary work, a versatile Field Programmable Gate Arrays (FPGA) based demo-board system has been developed in order to test and optimize the functionalities and the performance of the single sub-modules and wireless vision chain system. This work allows to demonstrate the feasibility of a complex biomedical system, with severe constraints by highlighting the necessity to enhance the frame rate in the future.

“…Many WPT systems based on inductive coupling were presented in literature for both of low (mill watts) and high power (multiple kilowatts) applications, such as charging mobile phones and powering electric vehicles, respectively [32]- [33]. A PTE of more than 75% was obtained for these systems at a distance of less than 10 cm between the transmit and receive coils [34].…”

“…A PTE of more than 75% was obtained for these systems at a distance of less than 10 cm between the transmit and receive coils [34]. A mobile phone charger was developed in [32] at 1.2 MHz. For this system, an output DC voltage of 3.79 V was obtained at the load when the distance between the TC and RC was 5 cm.…”

The impact of the natural disaster is devastating. Wireless power transfer technology is very promising to reduce this impact by providing power backup for communication devices. This paper presents the assessment of the wireless power transfer technologies for long distance energy transfer. The review of several wireless power transfer technologies (WPTT), namely inductive, capacitive, acoustic, and optical, are presented. The WPTTs are evaluated in the context of several criteria, specifically, propagation area, power level, and efficiency. From the evaluation, it is evident that, optical WPTT is highly suitable for long distance power transfer. It can cover a large area with considerable power. Moreover, it can be merged with the PV technology on the receiving end, which proves its superiority over other technologies in the context of application compatibility.
