Moreover, it portrays as a bridging technology to connect different scientific and industrial fields, e.g. Engineering, Medicine, etc. Consequently, additive manufacturing finds its applications in the production of patient-specific orthoses. This paper discusses the development of a pressure sensor based on an optical waveguide principle manufactured using stereolithography apparatus process to embed into a below-knee orthosis. For Orthopedic patients, the below-knee orthosis must be adjusted to the lower leg at regular intervals due to anthropometric changes in patient’s body to achieve proper mobility and correct load. Currently, this alteration relies on the patient’s estimation of support load which is only sub-optimal. Hence, the concept of developing an intelligent orthosis with a novel embedded optical system to monitor the exact support load at the neuralgic is proposed."}],"author":[{"first_name":"Akshay Manoj","last_name":"Shahane","id":"82525","full_name":"Shahane, Akshay Manoj"},{"last_name":"Shrotri","orcid":"0000-0003-2116-156X","full_name":"Shrotri, Abhijeet Narendra","id":"74090","first_name":"Abhijeet Narendra"},{"first_name":"Christian","last_name":"Wittenbröker","full_name":"Wittenbröker, Christian","id":"83111"},{"last_name":"Stübbe","orcid":"https://orcid.org/0000-0001-7293-6893","full_name":"Stübbe, Oliver","id":"51864","first_name":"Oliver"}],"title":"Manufacturing of solid core optical waveguide based pressure sensor for 3D-printed below-knee orthosis","type":"conference_editor_article","place":"Bellingham, Washington, USA","date_created":"2024-06-24T08:17:52Z","publication_identifier":{"eisbn":["9781510673090"],"eissn":["1996-756X"],"isbn":["9781510673083"],"issn":["0277-786X"]},"date_updated":"2024-07-17T13:02:26Z","publication_status":"published","volume":12995,"series_title":"Proceedings of SPIE"},{"date_updated":"2024-04-19T11:54:33Z","publication_status":"published","volume":11677,"series_title":"Proceedings of SPIE","date_created":"2022-04-19T10:20:55Z","publication_identifier":{"eissn":["1996-756X"],"eisbn":["978-1-5106-4190-7"],"isbn":["978-1-5106-4189-1"],"issn":["0277-786X"]},"title":"Manufacturing of lens array prototypes containing spherical and fresnel lenses for visible light communications using stereolithography apparatus","author":[{"id":"74090","full_name":"Shrotri, Abhijeet Narendra","orcid":"0000-0003-2116-156X","last_name":"Shrotri","first_name":"Abhijeet Narendra"},{"first_name":"Micha","full_name":"Beyer, Micha","id":"71403","last_name":"Beyer"},{"last_name":"Schneider","id":"71057","full_name":"Schneider, Daniel Johann","first_name":"Daniel Johann"},{"last_name":"Stübbe","orcid":"https://orcid.org/0000-0001-7293-6893","id":"51864","full_name":"Stübbe, Oliver","first_name":"Oliver"}],"place":"San Francisco","type":"conference_editor_article","department":[{"_id":"DEP5020"},{"_id":"DEP6020"},{"_id":"DEP5000"}],"year":"2021","abstract":[{"text":"Additive manufacturing (AM) and rapid prototyping process (RPP) have revolutionized the production of 3D objects in the last few decades. RPP has considerably increased the rate of production and the possibility of manufacturing prototypes in the fields of electrical, optical, and mechanical engineering. The manufacturing of optical prototypes including spherical, aspheric, and special kinds of lenses and lens arrays has reformed the fabrication of optical components. In this paper, specifically designed lens array prototypes for application in visible light communication (VLC) are introduced. These lens array prototypes are manufactured using the stereolithography apparatus (SLA) process. These lens arrays are designed to achieve optimal transmission of the light beam for VLC systems. One of the prototypes from the lens arrays contains primarily four spherical lenses and one thicker convex lens and the other contains one fresnel lens as a substitute for thicker convex lens. These lens arrays are further post-processed to achieve the required transparency. These lens array prototypes are tested using laser and LEDs. The ON-OFF keying modulated light beam was transmitted through the lens array at the sender side and focused on the photo-receiver using another lens array at the receiver side which is 200 cm apart. After evaluating these lens prototypes, it can be concluded that with appropriate post-processing and high-resolution stereolithography based manufacturing, a low data rate VLC link can be formed.","lang":"eng"}],"editor":[{"first_name":"Henry","last_name":"Helvajian","full_name":"Helvajian, Henry"},{"last_name":"Gu","full_name":"Gu, Bo","first_name":"Bo"},{"full_name":"Chen, Hongqiang","last_name":"Chen","first_name":"Hongqiang"}],"keyword":["Additive manufacturing","3D printing","Stereolithography apparatus","Spherical lenses","Fresnel lenses","Visible light communication"],"_id":"7670","user_id":"51864","publisher":"Society of Photo-Optical Instrumentation Engineers","language":[{"iso":"eng"}],"citation":{"ieee":"A.

However, to increase the performance, typically, beam-forming measures are\r\ntaken creating pencil beams, thus contradicting the illumination purpose. In order to optimize the performance\r\ntrade o\u000b between e\u000ecient illumination and communication, the switching capabilities of illumination LEDs are\r\nexamined. Illumination LEDs with standard drivers and without beam-forming show limited applicability for\r\ncommunication purposes as they are not optimized for the necessary switching capability (f \u0019 11 MHz) and\r\ncoherence. Methods to enhance the electrical current by pre-equalisation, biasing, carrier sweeping and current\r\nshaping are examined in respect to the illumination LED's communication performance. A novel driver scheme\r\nis derived which achieves considerably higher switching frequencies (f \u0015 100 MHz) without employing beamforming\r\nat the illumination LED. This driver is able to obtain a data rate of up to 200 Mbit/s at a distance of\r\n3.2 m, using on-o\u000b keying (OOK) modulation technique. Therefore, it is feasible to apply the LED driver by\r\nimplementing standardised illumination devices in VLC systems.","lang":"eng"}],"year":"2021","department":[{"_id":"DEP5020"},{"_id":"DEP6020"},{"_id":"DEP5000"}],"type":"conference","place":"Bellingham, Washington, USA","author":[{"first_name":"Daniel","id":"82849","full_name":"Schneider, Daniel","last_name":"Schneider"},{"first_name":"Abhijeet Narendra","full_name":"Shrotri, Abhijeet Narendra","id":"74090","orcid":"0000-0003-2116-156X","last_name":"Shrotri"},{"last_name":"Flatt","full_name":"Flatt, Holger","id":"58494","first_name":"Holger"},{"last_name":"Stübbe","orcid":"https://orcid.org/0000-0001-7293-6893","full_name":"Stübbe, Oliver","id":"51864","first_name":"Oliver"},{"last_name":"Lachmayer","full_name":"Lachmayer, Roland","first_name":"Roland"}],"title":"Efficient visible light communication drivers using illumination LEDs in industrial environments","publication":"Integrated Optics: Design, Devices, Systems and Applications VI","doi":"10.1117/12.2588923","intvolume":"     11775","citation":{"mla":"Schneider, Daniel, et al. “Efficient Visible Light Communication Drivers Using Illumination LEDs in Industrial Environments.” <i>Integrated Optics: Design, Devices, Systems and Applications VI</i>, edited by Pavel Cheben et al., vol. 11775, SPIE, 2021, <a href=\"https://doi.org/10.1117/12.2588923\">https://doi.org/10.1117/12.2588923</a>.","chicago":"Schneider, Daniel, Abhijeet Narendra Shrotri, Holger Flatt, Oliver Stübbe, and Roland Lachmayer. “Efficient Visible Light Communication Drivers Using Illumination LEDs in Industrial Environments.” In <i>Integrated Optics: Design, Devices, Systems and Applications VI</i>, edited by Pavel Cheben, Jiří Čtyroký, and Iñigo Molina-Fernández, Vol. 11775.
