I would like have ultrasound transducers/generators and sensors in the 1khz-100khz range. Response must not be flat in the frequency range.
I do not know what technology I have to use. Does ceramics covers the range?
I would need a microdrill that drills in 20mm diameter.
I can not find any tricone bit to do that.
Can any company build a custom one?
It is possible drill rocks through water by using ultrasounds? I can generate 1-10kW and up to 200khz
