With medical devices, a determination of medical risk is needed to decide whether something needs to be passed by the FDA or whatever it can be handled only by a for-profit review board and also usually an institution IRB prior to trial (there are almost no respected medical institutions that do not have their own irbs). I suggest a new branch for 'mind control' applications, based on device laws (minus pre1976 'grandfathered in laws') and old school psychological experiments deemed unethical after the fact (tuskeegee moment for tech bros (females included in the term I assume)). Do not even try to pull whatever crap is happening with , like, smartwatch trials where they are not including an involved principal investigator.
