  text: 'Additive manufacturing enables direct prototyping of complex 3D-objects that
    are difficult to manufacture using conventional methods. It is widely used to
    fabricate cost-efficient prototypes and 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 application of the stereolithography apparatus
    process to develop a pressure sensor based on an optical waveguide principle to
    embed into a below-knee orthosis. For Orthopaedic 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 and 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. '

  text: The ability to manufacture complex 3D-objects directly from its CAD model
    is the important reason why additive manufacturing is being widely used to fabricate
    cost-efficient prototypes and preferred over conventional manufacturing methods.
    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.
