(a) Architecture of the wireless bioresorbable Mg pressure sensors, whose initial resonance frequencies in air are presented later in Table 1. (b) Examples of the pressure response of the sensor in air before immersion and in Sörensen buffer solution after 1 and 10 days of immersion. (c) Measured pressure sensitivities of the sensor immersed in Sörensen buffer. (d) Drifting of the pressure sensor resonance frequency under immersion without applied pressure. (e) Water uptake properties of PDTEC. (f) Measurement setup for all the mechanical tests, where the three-point bending of the PDTEC samples was performed under immersion at +37 °C. (g) Flexural moduli of the immersed PDTEC samples. The initial, day 0 dry value was measured at +21 °C. (h) Flexural stress–strain curves of PDTEC as tested under immersion at various time points. (i) Stress relaxation behavior of PDTEC in aqueous conditions under a static 2 mm displacement.
