Dear follow engineers. I need your kind help. I have a device which emits rf energy when touching the skin. Because of this energy, the tissue heats up. Now, there are 2 options: 1. If I place a non conductive lotion on the skin (high impedance), and then apply the rf energy, most of it will...

Hi all, I have a strange situation.when I test my device for patient leakage current, I fail the test hence there is leakage current flowing through gnd. I tried to disconnect the gnd from device and retest and surprisingly it didn't change ..any idea?

Hi all, I have a tense circuit which outputs a bi phasic square signal at 12.5 hz. Apperantely it is creating a leakage current on the gnd line through the capcitors/resistors at the outputs which are connected to gnd.when u removed them, to keep the output floating, I receive a signal with...

Hi all i hope fhis is the correct place for this kind of questions.. i have a project where i need to glue a capsule or a tablet which is round shaped to a round shaped plastic mediator.this whole assembly at the end will be clinked to an handle to preform a certain task.the problem i have is...

Hello All I am to design a simple and cheep (as possible) a signal generator that would produce an output RF signal @ 1MHZ that would be able to produce about 30-35W dissipated upon 200 ohm load. Its possible to use 2 sync modules that produce less power each one that would work together with...

I have a devices that incorporates hand pieces that are used very rigorously , and I am experiencing a cable fatigue phenomenon. The hand piece is moving in circular motion on the patient body .The breaking point occurs at the entrance point of the cable onto the plastic housing. I seek for a...

Hello All I would like to have your opinion on the following: I need to choose a cable that could carry low voltage signals for monitoring as well as up to 300 VPP AC signal, 1 MHZ.What would be the best cable to do it? twiste pair ect....I have encountered the following website that could help...

Hi All! I need to measure a 1MHZ RF signal with an RMS value of up to 100V. This can be done easily using scope, But I need a much "easier" and idiot proof method using tools that anyone has like DVM. I though about building a full bridge rectifier but I will be happy to hear your input with...
