Fig. 4. Wireless measurements of pressure and temperature from a non-amputee individual.

Fig. 4

(A) Schematic illustrations of a non-amputee participant with three sensors on the right leg and NFC/BLE modules on the outside surface of a prosthesis simulator. (B) Pictures of a prosthesis simulator with attached NFC/BLE modules. (C) Representative pressure data collected while in a sitting position. (D) Representative pressure data collected while in a standing position. (E) Representative pressure data collected while walking on a treadmill (0.67 m/s). (F) Comparison of pressure data from the wireless sensor and from a wired pressure sensor array as a reference during leg flexing (90°). (G) Bland-Altman plot for pressure data from the wireless sensor and from the wired reference during leg flexing. (H) Temperature data from the wireless sensor and from a wired thermocouple as a reference collected while sitting, standing, and walking on a treadmill (0.67 m/s). All data were collected on two individuals, separately (n = 2).
