“…Scattering of photons in the tissue leads to loss of signal power which lead to high bit-error-rate (BER). Advances in the field of OWC and new technologies have led to studies of better communication through tissue and have reduced the BER [29][30][31][32] . Increasing beam permeability can contribute to further reducing the BER, and increase of communication reliability.…”

A major challenge in use of the optical spectrum for communication and imaging applications is the scattering of light as it passes through diffuse media. Recent studies indicate that light beams with orbital angular momentum (OAM) can penetrate deeper through diffuse media than simple Gaussian beams. To the best knowledge of the authors, in this paper we describe for the first time an experiment examining transmission of OAM beams through biological tissue with thickness of up to a few centimeters, and for OAM modes reaching up to 20. Our results indicate that OAM beams do indeed show a higher transmittance relative to Gaussian beams, and that the greater the OAM, the higher the transmittance also up to 20, Our results extend measured results to highly multi scattering media and indicate that at 2.6 cm tissue thickness for OAM of order 20, we measure nearly 30% more power in comparison to a Gaussian beam. In addition, we develop a mathematical model describing the improved permeability. This work shows that OAM beams can be a valuable contribution to optical wireless communication (OWC) for medical implants, optical biological imaging, as well as recent innovative applications of medical diagnosis.

“…To overcome these communication-related issues, researchers could explore wireless technologies compatible with wearable applications such as millimeter-wave frequency-based 60 GHz technologies [307][308][309][310] or optical wireless technologies, e.g., LiFi. [311][312][313] The optical communication method uses light in the infrared, visible, and ultraviolet ranges. Usually, the RF is the widely used wireless communication technology which is regulated between 30 kHz to 300 GHz in the electromagnetic spectrum range.…”

In the present era of the Internet of Things, wearable sensors have been receiving considerable attention owing to their great potential in a plethora of applications. Highly sensitive chemical type wearable sensors that can conformably adhere to the epidermis or textiles for monitoring personal microenvironment have gained incredible interest. Attributable to the large surface area and excellent mechanical, chemical, physical, thermal as well as biocompatible properties, nanomaterials have become a prominent building block to develop wearable sensors. In this review, recent progress in the development of nanomaterial enabled wearable chemical environmental sensors (WCESs) is presented by focusing on the chemistry‐based transduction principles. The developments in sensor structures, selection of materials, and fabrication methods are highlighted. The recent WCESs are summarized by grouping in three major types according to their transduction principles: electrical, photochemical, and electrochemical. In addition, sensors with multimodal sensing capability as well as sensors immobilized in wireless tags are summarized. Finally, issues, challenges, and future perspectives are discussed to develop next‐generation WCESs with long life, biocompatibility, self‐healing, and real‐time communication capabilities.

“…They can be based on VLC systems, using different techniques [ 109 , 110 , 111 ], OCC systems [ 112 , 113 , 114 ], or even combining optical and ultrasound techniques [ 114 ]. Regarding welfare tourism, there have also been several research papers related to the use of OWC in hospitals or health facilities that can also be used in adapted hotels or residences [ 115 ]. The use of VLC services for visually impaired people has been studied in depth in [ 116 ], while specific medical applications are described in [ 117 ], and remote patient monitoring in [ 79 ] for those who should be followed by their medical services on their origin countries.…”

In this paper, we explore the potential applications of Optical Wireless Communications in the tourism industry, considering both indoor and outdoor scenarios and different transmission speeds. They range from high-speed atmospheric outdoor links (Free-Space Optics (FSO)) to indoor systems based on high-speed lighting networks (known under the trade name LiFi©) or low-speed services support the Internet of Things networks, using visible light (VLC) or IR emitters, with receivers based on either on classical photodiodes or in image sensors, known as Optical Camera Communications. The avant-garde applications of this technology have been studied focusing on three possible use scenarios: the traveler himself, in what we have called TAN (Tourist Area Network); the tourist facility, which includes not only the hotel but also leisure areas (theme parks, museums, natural protected areas) or services (restaurants, shopping areas, etc.); and the entire destination, which can be both the city or the territory where the tourist is received, within the paradigm of the Smart Tourist Destination (STD). In addition to the classic services based on radio frequency and wired broadband networks, these technologies will make it possible to meet the tourist’s challenging needs, the establishment, and the destination. Besides, they cover the services imposed by the new marketing services related to location or context and feed the big data systems used to study tourist behavior.
