Ultrasensitive and compact device for noninvasive acquisition of low strength bio signals and method of using same

摘要

A method of detecting changes in biologically sourced electrical signals is disclosed. Biologically sourced electrical signals are coupled to a meta-stable and hair-trigger wise perturbable system. The system operates in a first oscillatory mode when the received signals have a strength below a first predetermined level and operates in a distinguishable second oscillatory mode when the received signals have strengths above the first predetermined level but below a second predetermined level. The strengths of the received and thusly distinguishable signals may be in a range below 10 picoAmperes. The biologically sourced electrical signals may be driven by intracranial nerve firings.

1. A method of detecting changes in biologically sourced electrical signals, the method comprising:
coupling, via an electrode, a biologically sourced electrical signal to a meta-stable and hair-trigger wise perturbable system, wherein the meta-stable and hair-trigger wise perturbable system has a first oscillatory mode when the coupled electrical signal has a strength below a first predetermined level and has a distinguishable second oscillatory or non-oscillatory mode when the coupled electrical signal has a strength above the first predetermined level but below a second predetermined level; determining whether the coupled electrical signal changes an operating mode of the perturbable system in a distinguishable way; and if there is a determined change of operating mode, correlating the determined change to a corresponding and predetermined range of sourced electrical signals that are predetermined to equivalently cause such a determined change.
