Intrinsically Stretchable Subthreshold Organic Transistors for Highly Sensitive Low‐Power Skin‐Like Active‐Matrix Temperature Sensors
Stretchable wearable sensors ultimately require low power consumption and high response
to physiological signals with skin conformability. However, power‐response tradeoff and
strain‐dependent sensing instability remain key challenges for electronic skin (e‐skin)
sensors. Herein, an intrinsically stretchable organic subthreshold transistor operating at low
voltage (− 1 V) is presented, leading to ultralow power consumption (< 1 nW) for highly
sensitive skin‐like temperature sensory devices. The highly temperature‐dependent …

Intrinsically Stretchable Subthreshold Organic Transistors for Highly Sensitive Low‐Power Skin‐Like Active‐Matrix Temperature Sensors (Adv. Funct. Mater. 1/2024)
In article number 2305252, Tae Il Lee, Jin Young Oh, and co-workers present an intrinsically
stretchable subthreshold organic transistor for a skin-like temperature sensor. The transistor
working in the subthreshold region enables highly sensitive temperature sensing with the
highest transconductance efficiency at near zero voltage, which leads to ultralow power
consumption. This allows for skin-like temperature sensors with active matrix arrays that map
the temperature distribution under 3D deformation.
