摘要：
Apparatus and methods for powering micron-scale implantable and injectable integrated circuit (IC) chips for in-vivo sensing and acquisition of various physiological signals are provided. The disclosed subject matter includes the integration of piezoelectric transducers, such as polyvinylidene fluoride (PVDF) or lead zirconate titanate (PZT), onto implantable and injectable IC chips for power transfer and data transmission using ultrasound waves generated from commercial ultrasound imaging equipment.
