Laminated Aluminum Foil Insulator Experiment With Noise Shielding Capability For Myoelectric Signal Socket Processing Device
Abstract: This research
investigates the problem of electromagnetic noise on myoelectric device. This
myoelectric device has a low pass filter response (Butterworth type) with
cut-off frequency (fc) 6 Hz and passing 8 volt signal. The passed signal, then
amplified by a differential amplifier for 150 times into 1,2 Volt (20% noise
captured system). So we require an approach to electromagnetic shielding to
reduce interference from the outside that enter into the device system. In this
study utilizing an experimental design using full factorial experiment methods
to determine the effect of the type of bahan, the frequency response, and the
interaction to the performance of shielding. The experiment results showed that
each element and their interactions, significantly affected the value of the
shielding performance. Aluminium foil air cell bubble has the highest shielding
performance with the average performance of shielding efficiency of 94,80887 %.
This bahan used for shielding socket design proposal which based in the
Wisconsin department of health service and American heart association standard.
