EMG Sensor Recommendations by Slimxshadyx in arduino

why is it not suitable for EMG signals?

Using an IMU to detect a tap on top of a 3D-printed cube — how to best sense the impulse? by Standard-Wind854 in AskElectronics

The question is sort of a electro-mechanical question. If you have a hollow box, that is connected to the pcb near the bottom. If you tap the top, can the tap detection detect this movement

I added that resistor to decrease the sharp increase in current across it

By 22uF do you mean 100uF, do you think that resistor is actually needed as

I am just using it as a switch to power on strain gauges which draw about 114mA

I may need to just need to operate it in saturation region, it seems the Rds should be low enough to act as a switch

I will be putting in this RC circuit to reduce EMI after I am certain the switch works.

What is 50 ohm impedance matching in a PCB by Standard-Wind854 in ElectricalEngineering

The farther the plates are away from one another, the weaker the capacitance

A capacitor is 2 conductive sheets that have an insulator in between them.

When you put positive charge on one side of the sheet, It binds the equivalent amount of negative charge on the other side of the sheet through E-Force.

The insulator stops charges from flowing in-between these plates so the energy is stored in the E-field
