Using EEG Neuro-Feedback technology to control a prosthetic hand
Unaffordable healthcare and excessive plastic waste are both alarming issues that are plaguing modern society. Recent studies conducted by the World Health Organisation (WHO) report that about 15% of the world's population suffer from a form of disability, of which 50% of the demographic cannot afford adequate health care. Furthermore, 8 million metric tons of plastic annually enter our oceans (apart from the 150 metric tons that currently circulate our oceans!). In conjunction to the global plastic pollution crisis, unnecessary invasive surgery is currently being done on amputees. Many of these desperate patients are forced to pay exorbitant prices in order to live a normal life with bionic prosthetics. The solution… Project Limbs - an EEG, 3D printed prosthetic printed from recycled plastic. Signal processors will be implemented to build an affordable and easy-to-use ‘mind controlled prosthetic hand’, that requires no invasive surgery.
Synthesis of Mesoporous Carbons and Their Application for EDLC
The quick increasing energy consumption arouses the interest in the development of power storages. Electrochemical supercapacitor is one of clean and sustainable candidates of energy storage system, and porous carbons are the most potential candidate as electrode materials for electrochemical supercapacitor because of their large surface areas, high chemical and physical stability, good conductivity, as well as low cost. In this work, we synthesized the mesoporous carbons by using ZnO nanoparticles as sacrificing template via nano-casting synthetic process and natural porous carbon materials. The synthesized porous carbon has a mesoporous structure. Because the surface area and pore size of the synthesized mesoporous carbon are larger than that of the coconuts fiber-derived carbon, the CV plots show that the synthesized mesoporous carbon has a good rectangular shape and a much better performance than that of the coconuts fiber-derived carbon. We also develop an easy way to discriminate how well a supercapacitor works. We applied these porous carbon-based electrodes on both handmade as well as the commercial capacitors and measured their electrical performances. The handmade EDLC is less efficient than the commercial capacitor.
