This makes the current Internet infrastructure obsolete. Therefore, the TSensor Systems infrastructure is one of the major hurdles to the Abundance that TSensor development promises. We are capturing the inputs from a variety of sources including white papers, popular journals, emerging academic journals and interview with futurists in the field. Then we are placing that information into the framework of a thirdgeneration-type technology roadmap. The TSensors System Roadmap is a plan for accelerating progress, based upon technological, market, business value systems, regulatory and political drivers that are relevant to developing new IOT (E) infrastructure subsystems, systems and designs. This work is the product of the TSensor Systems Working Group, an adhoc group of Mancef members meeting at annual COMS conferences. 2 We define TSensor Systems as the infrastructure required to support the manufacture and operation of TSensors. Thus the TSensor Systems Roadmap is currently divided into several chapters, corresponding to multiple root technologies: ◦ ◦ ◦ ◦ ◦ ◦ 3D printing infrastructure for low cost sensor manufacture Energy harvesting as a source of power for the TSenor revolution New technologies for energy storage Ultralow power wireless communication technologies New network protocols and standards/Operating Systems Analytics We also present critical dimensions and boundary conditions. 3 Multiple Root Technologies Strict Boundary Conditions Presentation Flow Critical Dimensions Roadmap 4 Multiple Root Technologies Strict Boundary Conditions TSensors Summit, La Jolla 2014 Critical Dimensions Roadmap 5 Multiple Root Technologies In Strict Boundary Conditions Critical Dimensions Roadmap addition to discussing technologies, we would also like to evaluate technologies using: ◦ Technological Readiness Levels ◦ Task-Technology Fit Problem: we cannot properly evaluate the adequacy of the current technology, because we do not yet know enough about the future! 6 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Technology readiness levels (TRLs) are measures used to assess the maturity of evolving technologies (devices, materials, components, software, work processes, etc.) during their development and in some cases during early operations. Generally speaking, when a new technology is first invented or conceptualized, it is not suitable for immediate application. Instead, new technologies are usually subjected to experimentation, refinement, and increasingly realistic testing. Once the technology is sufficiently proven, it can be incorporated into a system/subsystem. http://en.wikipedia.org/wiki/ Technology_readiness_level 7 Multiple Root Technologies Strict Boundary Conditions “The task-technology fit (TTF) model is a widely used theoretical model for evaluating how information technology leads to performance and usage impacts. For an information system to positively affect technology utilization, the technology must fit the task it supports to have a performance impact.” Computers in Human Behavior 34 (2014) 323–332 Critical Dimensions Roadmap 8 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap 3D printing technology is considered one of the exponential technologies (in book Abundance). 3D printing technology promises disruption in deployment of sensors and electronics, wherein sensor arrays and signal processing electronics could be printed on flexible substrates, enabling unit prices of the entire systems (e.g., printed on food packaging sensing freshness and quantity of food and communicating with external readers) to drop below $0.01, thus enabling disposability and trillion unit level deployment. 3D printed electronics needs increased awareness in the sensor community to accelerate its deployment. This Chapter’s objective is to fill this gap with an overview what is becoming available, and to use that information in the TSensor Systems Roadmap. 9 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap 3D printing of nanoscale objects by depositing electrospun polymer nanofibers.

Roadmap 11 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Massive deployment of sensing systems will not be possible without the “power for life”: energy sources generating energy from the environment such as light, movement, heat and RF. Sensor application often restrict the size, weight and of course cost of energy harvesters. Currently there is a gap between what current technologies can deliver and what is needed by wireless systems. This chapter focus is on increasing awareness of advancements in energy harvesting, with the objective of accelerating their commercial deployment. 12 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Flexible electronic devices and storage using nanowires. TRL 4. Fiber-like supercapacitors, assembled from graphene/carbon nanotube fibers, having both high power density and high energy density.

TRL 4. 13 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap As discussed under Energy Harvesting, there is a gap between what current technologies can deliver and what is needed by wireless systems. Improvement of Energy Harvesting technologies is one approach to bridge the gap, but the other one is lowering the power of wireless communication. The objective of this Chapter is to increase awareness in sensor community on advancements in wireless communication, with the objective of accelerating their commercial deployment. 14 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Flexible passive organic and MEMS RFID tags (Zhan et al. 2014).

TRL 4. 15 Multiple Root Technologies Strict Boundary Conditions Network connectivity is the area which receives the largest funding ($ billions) from multiple organizations and Governments. The disruptive advances in Internet Network architecture has been either deployed or is under deployment by major network providers: ◦ Addition of the Fog network layer under Cloud. ◦ Addition of Swarm network layer under Fog for edge devices. Critical Dimensions Roadmap These changes create dramatic simplification for network connectivity of sensors. ◦ For example, deployment of parking sensors by Streetline http://www.streetline.com/ was estimated (by Cisco speaker at 2013 TSensors Summit at Stanford University) to cost less by $10s million and reached market several years earlier, if it would happened today. The objective of this Chapter is to increase awareness in sensor community on network infrastructure advancements, with the objective of accelerating their commercial deployment in sensor based systems. 16 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Micro-electrical-mechanical systems technology (MEMS) have enabled the creation of wireless sensor networks (Gubbi et al. 2013).

TRL 2. 17 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Sensor generated data are forecasted to reach 1 BB (bronto Byte) in less than 10 years. Extracting useful information from such “information overload” becomes essential for all applications, ranging from medical to pollution control and personal life management. Advanced data processing technologies and algorithms reach maturity, e.g., machine and deep learning (AI), promising revolutionary changes in our day to day lives. ◦ Google estimated (personal communication with Janusz Bryzek), that automatic on-spot interpretation of medical images (e.g., ultrasound) could be developed in 6 months using machine learning, if large enough data would be fed to computers. The objective of this Chapter is to increase awareness in sensor community on Analytics and Big Data advancements, with the objective of accelerating their commercial deployment in sensor based systems. It has been suggested that analytics on streaming data is key to the IoT (McNeill 2014). In addition to stream processing, other technologies include Hadoop systems, NoSQL databases, in-memory data grids and real-time data integration tools (Stedman 2014). 18 Multiple Root Technologies Strict Boundary Conditions Critical Dimensions Roadmap Linear Technology’s Dust Networks’ WirelessHART (IEC 62591) standard (http://en.hartcomm.org/hcp/tech/wihart/ wireless_overview.html).

Strict Boundary Conditions Critical Dimensions Roadmap 25 Multiple Root Technologies Strict Boundary Conditions TSensors Summit, La Jolla 2014 Critical Dimensions Roadmap 26 There are six ways in which the nature of many new innovations and products differ from earlier products and innovations: 1. These innovations are created at the interface of multiple root technologies. 2. These innovations often do not have a unit cell such as the transistor does for the semiconductor roadmaps. 3. Differing applications drive innovations that will require differing and often multiple critical dimension development for each technology being utilized. 4. The boundary conditions constraining today's innovations and products are much stricter than ever before . 5. Drivers are much more important to these new innovations. 6. New business models such as focused consortia are driving technological development without benefit of predetermined architecturally stable product process platforms.
