Painless Biosensing for Non‐Invasive Health Monitoring: Advances, Platforms and Future Directions
A review of the painless biosensing landscape to include interstitial fluid and breath/exhaled breath condensate is presented, and electrical, non‐faradaic transduction, including field‐effect transistor‐ and impedance‐based sensors are introduced, as a third major modality underpinning much of the current wearable sen...
