USC researchers have invented an IWT including a transceiver (TRX) that provides a unique connecting platform between medical and consumer electronics in a single chip, enabling a wide variety of applications. This device includes a fully integrated dual-band TRX with mutually-coupled on-chip antennas for IWT. It operates at 915 MHz and 2.4 GHz in both transmit and receive modes to enable bidirectional communication between medical and consumer electronics using a single chip. A power management unit (PMU) generates required power to supply the internal TRX, external sensors, and controller units from a single battery. The transmitter (TX) consists of a mutually-coupled dual-band oscillator using on-chip antennas as the inductors of the oscillators.




  • Bi-directional communication with simultaneous transmission
  • Smaller device size and packaging
  • Flexible packaging
  • Reduced power consumption

Potential Applications:

Progress in implantable and wearable technologies (IWT) has made such devices an important tool for physicians to monitor biophysical parameters, diagnose numerous health conditions, and treat diseases. There is currently a mismatch between medical devices and consumer electronics regarding operational frequency ranges which hinders their natural communication abilities, thereby requiring additional components to create full systems solutions.
