OCTOBER 2022 I DESIGN007 MAGAZINE 85 operating the equipment, and troubleshooting at every step of the process. Looking Ahead e continued convergence of evolving mar- kets and further refinement in the direct and associated technologies of conductive inks builds an opportunity that some will find com- pelling. Who will it be? Will current electron- ics designers and manufacturers expand their core competencies to include conductive inks and associated technologies? Will the growing ecosystem of flexible electronics organizations and individuals, such as members of the OE-A (the largest international association dedicated to the space), expand their scope and capa- bilities into historically traditional EMS/SMT provider arenas? So far, the adoption leaders are the product companies themselves. Our largest adopters are OEMs that have designed conductive inks into their products, and we are working directly with them and their Tier 1 suppliers. In most cases though, imposed confidentiality by the OEMs prevents the ink providers from announcing many details regarding specific customers and application cases. So, for now at least, who is using them? at's the secret. DESIGN007 Stan Farnsworth is chief marketing officer with PulseForge and a founder of NovaCentrix. With the explosive growth of the spectrum demand of the Internet of Things (IoT), Non-orthog- onal Multiple Access (NOMA) and spectrum sens- ing are considered as key candidate technologies to improve spectrum utilization in next generation wireless communications technology. However, given the complexity of future IoT scenarios, it brings new challenges on how to ensure the performance of spectrum utilization and system throughput in large-scale IoT scenarios when using both technolo- gies at the same time. Motivated by such a challenge, a joint research team from the Shanghai Advanced Research Insti- tute (SARI) of the Chinese Academy of Sciences, VTT Technical Research Centre of Finland and Uni- versity of Windsor of Canada, creatively proposed a novel spectrum sensing tech- nique for 6G-oriented intelligent IoT communications, seeking a feasible way to provide underly- ing support for perceptual inter- ference and intelligent identifica- tion between large-scale coex- istence and aliasing IoT users in future 6G scenarios. Focused on inter-system orthogonal/non-orthog- onal aliasing coexistence scenarios, the research- ers designed a multi-layer spectrum sensing tech- nology based on feature detection in NOMA sce- narios with multi-users. The corresponding rational workflows and transceiver structures according to different scenarios were presented, and the thresh- old expressions were deduced accordingly. Oriented towards the upcoming 6G complicated scenarios, the researchers designed one downlink mode and two uplink modes to describe relation- ships among users' priorities, power, and transmis- sion forms. Based on the characteristics of each mode, they further customized the detection probability opti- mization algorithm according to the characteristics of each scene, so that the pro- posed technology can effec- tively improve the detection probability of orthogonal/non- orthogonal hybrid IoT systems and improve the overall system throughput.
