Organ transplantation can considerably extend the recipient’s life, but organ failure can occur at any time, especially if the host rejects the organ. Madhvapathy et al. developed a bioelectronics-based approach to track acute kidney organ transplant failure by attaching a wireless, soft electronics interface to transplanted kidneys that allows real-time continuous monitoring of organ temperature and thermal conductivity (see the Perspective by Zaidan and Lakkis). Using rat models, the authors demonstrated early detection of transplant rejection by tracking changes in normal cycles or an elevation in organ temperature.
