  • Wearable impedance cytometer
    Patent number: 11506592
    Abstract: This disclosure provides an impedance cytometer which includes a carrier that can be attached to a living being, with a biosensor mounted thereto. The bio sensor includes a microfluidic flow channel, formed in the carrier, and an impedance circuit. The microfluidic flow channel accommodates passage of a particle therethrough. The impedance circuit, connected to the microfluidic flow channel, includes a signal generator that produces a high-frequency drive signal applied to the flow channel to produce a biosensor output signal having high-frequency variation resulting from the drive signal and low-frequency variation resulting from impedance variation within the flow channel during the particle's passage. A lock-in amplifier is disposed to (i) amplify the bio sensor output signal, (ii) mix the amplified signal with the drive signal, and (iii) frequency-filter the mixed, amplified signal to output an impedance signal representing the low-frequency impedance variation resulting from the passage of the particle.
