An ultimate goal of biological measurement is to monitor the states of a living body in a non-invasive, continuous, and accurate manner without disturbing the natural functions or activities of the living body. Because electronic devices in direct contact with biological tissues are inevitably exposed to physical disturbances caused by physical contact, considerable efforts have been made to minimize their effects [1]. In temperature measurement, for example, it is preferable to reduce the heat capacity or thermal conductance of a sensor to suppress the effect of heat transfer from the object [2]. Furthermore, mechanical compliance with electronics is important for biological objects, because the skin is soft and has a three-dimensional structure. Flexible and/or stretchable sensors have been proposed to reduce the effects of modulus differences between the skin and the electronics [3,4].
