In 21st century, development in technology has changed the attitude of living of human beings. We are experiencing those things, which we only dreamed about decades ago and was considered as impossible in real life. Wearable technology is that technology which has changed the lifestyle of human beings. Practically we are running to have speed to get as more as new modern technology that would be smarter, more flexible, more comfort and always connected with us! But it is hard reality that with increasing amount of wearable technologies, to keep us connected 24 hours, we need wireless power source to keep the device on! Therefore, the specific vision of our “SPEED” is to build an effective cooperation between science and society, to materialize new smart technology for science and to pair scientific nobility with social awareness and responsibility. Our proposed research approach and manufacturing product concept will address both technical performance and cost-effectiveness of energy harvesting wearable applications1,2, targeting accumulation of energy dissipated by the daily body movements into the sustainable electrical energy through high performance flexible wearable systems that could be integrated safely into everyday objects for an improved quality of life. The technology commonly referred to as Smart Power Emerging Energy Device (SPEED) aims to promote higher quality of life with built-in power generator that can harvest spontaneous electrical energy, that can instantly provide electrical power to the daily used smart electrical products. Here, we newly developed polymeric functionalized human-motion interactive textile energy generator (HiTEG) which is working under mechano-responsive charge transfer mechanism. Each functionalized textile fiber has been used to produce current by simple patting, bending, or even soft touching, using different mechanism other than conventional piezoelectric or triboelectric platform3. We have designed prototype device HiTEG, integrated with free-standing functionalized fibers which is working under human-motion interaction, produces a peak power density of ~0.6 W m-2 with output current density of ~22 mA m-2. Very cheap, easy synthesis and durability are the key factors behind this application. We have succeeded to power commercial portable digital meter, LEDs. Our prototype energy harvester device, HiTEG responds stably over 100 thousand times of patting, bending for six months without any degradation. The global economic transition due to climate change urgently requires a source of limitless supply of clean energy. Failure to develop such a source could be catastrophic to the existence of humanity. Therefore, specific objective of our research proposal is to build effective cooperation between science and society. The goal is to re-collect waste mechanical energy into smart electrical energy, purposing the concept of sustainable development in environment which is one reasonable way to address global economic issues. The concept and vision of the work not only strongly support the goal of “Affordable clean energy” (Goal 7) of 2030 Agenda, it will partially support the Goal 8 (Decent work and economic growth) and Goal 9 (Industry, Innovation, and Infrastructure). This ongoing research development will ensure the green environment by using textiles through cost-effective clean methods. Outcome of this project will benefit future socio-economic structure for the nation. Considering the existing huge garments market4, overall objective of SPEED is to contribute an emerging platform of wearable e-cloth technology as relatively new industry that will serve as a means of increasing social welfare and lead to important savings on welfare budget.
