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. Embodiments enable wearable, personalized cytometry."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wearable impedance cytometer","description":"This disclosure provides an impedance cytometer which includes a carrier that can be attached to a living being, with a biosensor mounted thereto.
