Triboelectric nanogenerators (TENGs) scavenge electricity from low‐frequency mechanical motions. This study proposes a simple and cost‐effective method to synthesize a dual‐surface modified Ecoflex polymer (SME Sponge) with a porous inner structure and micro pyramidal projections on its surface. An Ecoflex‐Aluminum‐based contact separation triboelectric nanogenerator (EA‐CS TENG) is fabricated to investigate the impact of pores and micro pyramidal projections on triboelectric performance. The performances are evaluated with and without an air gap between the materials. Despite the gapless responses being lower than those with the air gap, the gapless system demonstrates the capability to charge a 0.1 µF capacitor up to 0.8 V with mechanical forces of 9 N, validating the potential of surface‐modified porous triboelectric materials for gapless TENGs. Additionally, the device with an air gap achieves a charge of 0.1 µF up to 3.3 V with mechanical forces of 9 N. Finally, a completely self‐powered tally counter is employed to verify the powering and sensing applications of EA‐CS TENG with an air gap. This study confirms the feasibility of utilizing low‐cost EA‐CS TENG as a renewable energy source for generating electricity from mechanical motions and driving devices without the need for batteries.
Presently, due to the after effect of the inventions, various techniques are a used for control of home appliances. Particularly, they are particularly designed for the aged people and also for patients. In some cases advanced systems are built for the physically disabled people. The main problem in all current systems is that they are not suitable for all kinds of people and under all conditions. Each system needs a unique design and device, which increases the cost of constructing them and reduction in stability. The main aim of our project is to make a a simple system, which can be used by all types of people in every situation for controlling devices around them.Brain waves can be used to solve this problem. Here, the brain wave has an important role in controlling devices in the home condition and enable communication among people suffering from pseudo coma. The brain waves are detected by use of Neurosky Mindwave sensor and data is transferred using Bluetooth to the CA system. The CA system is made up of an Arduino and its programmed to control all the devices connected. The main advantage of the project is that it can be used by all types of people.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
