Overview

Randomized trial demonstrates enhanced thermoelectric properties in flexible detectors, indicating potential for health monitoring applications.

Key Points

  • The study aims to improve the performance of flexible photothermoelectric detectors through germanium incorporation in tellurium films.
  • Developed Te 0.99 Ge 0.01 and Ag 2 Se paste formulae for detector fabrication
  • Applied screen-printing method on flexible polyimide substrates
  • Conducted a thermal treatment process to enhance film properties.
  • Te 0.99 Ge 0.01 showed a power factor of 2.25 µW cm −1 K −2; Ag 2 Se exhibited 23.8 µW cm −1 K −2
  • Single-pixel FPTE detector achieved responsivity of 2.49 V W −1 and low internal resistance of 55.7 Ω
  • Detectivity of the detector was measured at 2.38 × 10 8 Jones under 980 nm infrared radiation.
