TOP6: Sensors and Sensor Systems - IEEE Virtual World Forum on Internet of Things 2020

Date: Tuesday, 7 April 2020
Time: 8:30am-6:30pm
Room: Newberry Room

Description

Sensor and sensor systems are an essential and often critical part of IoT solutions and
applications. If one views IoT as the enabling technology and infrastructure for operating end-
end platforms that take advantage of the Internet’s global reach – then sensors are the
essential source of data and information that drives the value chain and ultimate utility of
solutions and applications. The aspects of what the Track will cover include:

The underlying technology and principles of novel (analog and digital) physical and
virtual sensors. This includes sensors that may measure simple physical quantities
(pressure, temperature, moisture, chemical composition, etc), complex sensors such as
LIDARs, radars, imagers exploiting different portions of the electro-magnetic and sound
spectrum (including vibrometry), as well as hyperspectral, multi-modal and information
sensors (extracting information from data in digital form), and lastly sensors that can be
used to deduce or identify a specific condition or specific information (such as a failure
mode of a piece of equipment, the presence of an object or feature, or an identity)
How the sensors or sensor systems may be used in an operational setting addressing
system level issues and tradeoffs. This includes the choice of overall architecture, the
role of accompanying technologies as well as capital and operating expenses acceptable
for effective solutions and applications. As important is the ability to meet both
functional and intrinsic requirements and successful economic and business models for
deployment. Other issues addressed in the track involve standardization, policy and
regulations, security and privacy, the ethical uses of sensor technologies, and the
societal consequences of widescale use. With large investments in industrial IoT,
connected health, autonomous cars, retailing, and consumer services comes the need to
deal with the fundamental complexity and distributed nature of IoT applications – and
the understanding of what is technologically mature and market ready and what is still
in the offing.
Applications of sensors and sensor systems to specific functions in various verticals and
markets stressing experiences from trials and demonstrations. For WFIoT2020 we put a
premium on sensors for the market/vertical segments that are a part of the conference
such as: Agriculture, Energy and Power, Environment and Ecology, Healthcare, Industry
and Manufacturing, Smart Cities and Smart Buildings. This also includes horizontal
services and infrastructure such as options for connectivity (fixed, wireless, space based,
and terrestrial mobile), access to computing and storage (embedded, local, edge, fog
and cloud), as well as platforms and frameworks for exploiting other important
technologies such as Artificial Intelligence and Machine Learning, Virtual and
Augmented Reality, Data aggregation and curation, support for industrial automation
and for autonomous platforms.

Talk Title: VCSEL based Optical Sensors for IoT

Abstract: In recent years, Vertical-Cavity Surface-emitting Laser (VCSEL) technology is proliferating for high-volume applications and put into commercial use in various industries such as smart sensors in Building Automation, Consumer Electronics, Manufacturing, Automotive and Transportation, Healthcare & Medical, Retailing & Logistics, Security & Surveillance, Agriculture, Aerospace & Defense, Oil and Gas etc. The increasing adoption of automation across the above industries is driving the growth of global technology intensive optical sensor market to ~ USD$36B by 2026. These built-in smart optical sensors with their inherent advantagess of flexibility, compactness, light weight and high performance in adverse environments, together with connectivity to high-speed Internet to perform seamless operation of various pre-programmed functions, are strongly influencing the landscape of Internet of Things (IoT). As industry 4.0 begins attaining importance and the data collected from these smart optical sensors will be processed and used for specific applications through IoT cloud platform, the relevance of intrinsic and extrinsic optical sensors is increasingly important in manufacturing applications across industries.

IoT systems use various Optical Sensors viz., Photon Emitters (LED, laser diodes [VCSEL, FP, DFB]) and Photon Detectors (PD, APD, SPAD, SiPMT) as high-speed, low-cost and reliable wireless communication components with the necessary electronic driver circuits for accurate sensing applications such as touch, gesture, depth etc. Nowadays, 1D sand 2D VCSEL arrays between UV-NIR/IR wavelengths as intrinsic optical sensors are finding high value commercial opportunities in Smart Consumer Electronics applications (mobile, watch, tablet, voice-assisted devices), Biological feature identification (security and tracking), Healthcare (pulse oximeter, OCT), Automotive (imaging in autonomous cars), Transportation/Traffic management (in anti-collision avoidance, speed and position measurement), to Environment (green building automation), Defense (security & surveillance), Logistics/Shipping (containers, seals, inspection of object movement), Home Automation (3D image tracking, detection of objects nearby), wireless (navigation, illumination, GPS positioning), Entertainment (gaming, gesture control, remote control, eyewear through AR), Food/Chemical Inspection etc. In IoT, as the future electronic components operate numerous systems with intelligence without human intervention, market players extend the capabilities of intrinsic optical sensors and their improved performance to measure extrinsic optical sensor functions such as temperature, flow, liquid level, pressure etc. for effective transmission of data to designated modules. In this talk, the speakers will present the current state of NIR VCSELs for Consumer Electronics (mobile sensing) & Automotive Industries (LiDAR) for 3D object detection and imaging up to 200 m. They will discuss the accomplishments so far and future challenges ahead in this field. Examples will also be shown on the control of a wide range of Field of View (FOV) for Advanced Driver-assistance Systems (ADAS) and green building automation.
