In vitro and in vivo evaluation of wireless, battery-free wound lactate monitor. (A) Functional block diagram showing the working principle of the wireless electronics for power and data transfer. (B) Correlation between signal output from sensor and that measured by the wireless device (data presented as mean ± S.D., n=3). Effect of performance of the device based on its (C) relative inclination with respect to the transmitter antenna (data presented as mean ± S.D., n=3) and (D) spatial location inside the experimental arena. (E) Photo of the wireless sensor attached to a wound in a diabetic mouse. Scale bar: 5 mm. (F) Daily monitoring of wound lactate in a diabetic mouse over 4 days (data presented as mean ± S.D., n=60).
