Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Optical wireless localization

Wireless Networks, 2011
In this paper, we explore the possibility of using directionality of free-space-optical (a.k.a. optical wireless) communications for solving the 3-D localization problem in ad-hoc networking environments. Range-based localization methods either require a higher node density (i.e., at least three other localized neighbors must exist) than required for ...

Hybrid Optical Wireless Networks

International Conference on Networking, International Conference on Systems and International Conference on Mobile Communications and Learning Technologies (ICNICONSMCL'06), 2006
This paper describes a dynamic reconfiguration algorithm for a hybrid fiber wireless network, which takes advantage of dynamic reconfiguration in WDM based optical networks to provide bandwidth on the fly. The WDM technique for optical networks allows network operators to extend the existing capacity of passive optical networks manifolds.

Capacity of wireless optical communications

IEEE Journal on Selected Areas in Communications, 2003
We consider the ergodic capacity and capacity-versus-outage probability of direct-detection optical communication through a turbulent atmosphere using multiple transmit and receive apertures. We assume shot-noise-limited operation in which detector outputs are doubly stochastic Poisson processes whose rates are proportional to the sum of the ...

Wireless optical communications: a survey

2004 IEEE Wireless Communications and Networking Conference (IEEE Cat. No.04TH8733), 2004
The demand for wireless broadband communications has been growing steadily for last several years. The congestion and the limitations on bandwidths of the radio spectrum have inhibited unrestricted growth of radio wireless systems. Wireless optical, however, holds the promise of delivering data rates that can meet the broadband requirements.

An Optical Wireless Temperature Sensor

2019 IEEE SENSORS, 2019
This paper presents a wireless temperature sensor that uses a GaAs solar cell as a wireless transmitter of information. Transmission of information with a solar cell is possible by modulating the luminescent radiation emitted by the solar cell. This technique, dubbed Optical Frequency Identification or OFID, was recently reported in the literature and ...

Cognitive optical wireless network

2016 18th International Conference on Transparent Optical Networks (ICTON), 2016
Optical wireless network has the potential to serve both data centers and metropolitan area networks. Free space optical networks has one dimension that is not encountered in fiber networks and that is its ability to reconfigure its connection topology by beam steering in time scale of at least mS if not µS.

Reconfigurable optical wireless

1999 IEEE LEOS Annual Meeting Conference Proceedings. LEOS'99. 12th Annual Meeting. IEEE Lasers and Electro-Optics Society 1999 Annual Meeting (Cat. No.99CH37009), 2003
We propose a natural step in freespace optical communications that is wireless. Namely, we propose the use of inertialess optical scanners as the agile free space light routing method within a multi-user free-space optical wireless network to realize all-optical advanced wireless networking. For instance, optical intersatellite links can use the highly

Optical Wireless Communication

Proceedings of the 24th Annual International Conference on Mobile Computing and Networking, 2018
Data is the new currency impacting everybody's lives. As the modern world receives & sends millions of Terabytes of data every day, the present-day wireless data communication technologies comprising of Wi-Fi & 4G-LTE is on the verge of becoming partially inept for information exchange as they suffer from spectrum congestion in both controlled and ...
