muscle fibres to contract. EMG is the signal made, it can be measured by applying conductive elements or electrodes to the skin surface, or invasively with the muscle. When using EMG, tiny devices named electrodes are used to transmit or detect electrical signals. Three factors that may influence its accuracy: 1. The placement of the electrode on the skin, overlying the muscle. 2. ¬¬¬The electrode shape and size. 3. Physiology mind set of the character of EMG. Results…

advantages over the then only rechargeable battery, lead acid, but the materials were expensive and the early use was restricted. Developments lagged until 1932 when attempts were made to deposit the active materials inside a porous nickel-plated electrode. Further improvements occurred in 1947 by absorbing the gases generated during charge. This led to the modern sealed NiCd battery in use today. For many years,…

Ions are shuttled back and forth within the electrochromic layer when potential is applied. Typically, an electrochromic system is fabricated from five layers which comprises of two transparent conductors, an ion conductor or electrolyte, a counter electrode and an electrochromic layer as shown in Figure 1.[7] Figure 1: Five layers in an electrochromic system 2.1.2 Working Principle of Electrochromic System Figure 2: Movement of electrons and protons in electrochromic system Figure 2…

[20], and various methods have been used to fabricate different PB-based hybrids for PB-modified electrode so far. Almost all the procedures adopted for the PB deposition on electrode surface are based on electrochemical methods [21], involving a constant applied potential [22–24], or potential cycling [25,26] in a solution of ferric and ferricyanide ions. Another approach for the PB deposition…

value rendering results incorrect. Corrosion on the alligator clip that was used could prevent consistent contact of the electrode thereby giving fluctuating results throughout the experiment. Electrode touching the salt bridge in the beaker while a measurement was taken can also influence the measured voltage by the voltmeter. Mix matching the voltmeter clips to the wrong electrode will possibly yield wrong negative values thereby indicating non-spontaneity of the reaction. Human errors due to…

Calf strains are a very well known problem for runners, soccer and basketball players, gymnasts, and dancers, and even more common in athletes who are advancing in age. The calf muscle consists of nine different muscles; the gastrocnemius, soleus, and plantaris muscles attach onto the heel bone and they all work together to produce the upward and downward motion of the foot (calf raise). The other six muscles cause knee, toe, and foot movements in different directions, however those muscles are…

In Intra-body communication the transmission medium used is human body, which has made much attention in personal area network(PAN).Since the signals pass through human body, the noise or the disturbances that interrups,obstructs,or the limits that effect the performance and interference is less to wireless technologies because the data is largely contained /transmitted with help of human skin. The characteristics of intra body communication are superior to those of other radio-based network…

hearing or deaf hear sounds. The implant works with a microphone, speech processor, stimulator, and electrode array. Sounds around the person are picked up by the microphone. The sounds that are picked up by the microphone are arranged in the speech processor. Singles from the speech processor are changed to electric impulses in the stimulator. The auditory nerve receives the impulses from the electrode array. A cochlear implant can cost up to 100,000 dollars and it is a big risk. Headaches,…

The electrodes consist of a metallic collector, which is the most conductive part of a functional material, the high surface area part may also be found here. Both electrodes are separated by a membrane, the separator allows the movement of the charged ions it does not allow the conductance of the electricity. The supercapacitor’s voltage…

As we know, Parkinson 's disease is a globally occurring mental defect that affects human 's central nervous system. Currently, there is no cure for the disease, and we can 't even diagnose the cause of this disease. DBS is still a developing technology being widely employed to fix neuropsychiatric disorders. It is a surgical therapy employed to curb this deadly disorder as well as essential tremor. The method involves the patients undergoing surgery. This surgery uses some high technology to…
