This paper presents a low-power MCU with remotely-programmable feature which is specifically optimized for implantable medical devices (IMDs). In medical applications the most critical requirements are low-power, energy-efficient, flexible, etc., which are provided by utilizing the techniques such as clock gating, power gating, instruction set improvement, DMA optimizations for data paths. The MCU...
Low power consumption and efficient power supply are very crucial for biomedical implant electronics. The power issues in the design of implanted devices are addressed and three distinct design cases, including a low power stimulator chip for retinal prosthesis, a novel cochlear implant system with multi-level power optimization and a wireless monitoring system of total knee replacement, are demonstrated...
A low power IC of the wireless monitoring system of the orthopedic implants (WMSoOI) is put forth. The analog-digital mix-mode system monitors the implant duty cycle, detects abnormal asymmetry, wear, and high amounts of force, and other conditions of the orthopedic implants. Data for diagnosis is communicated wirelessly between the embedded chip (inside body) and the remote circuit (outside body)...
