For example, in wearable health devices, which continuously monitor a patient’s vitals, the integration of envelope tracking can extend battery life, ensuring that the device remains functional for extended periods without the need for frequent charging. This is essential in settings such as home care, where devices are used around the clock.
2. Improving Efficiency and Performance in Medical Imaging
Medical imaging systems, such as MRI machines, CT scanners, and ultrasound devices, rely on high-performance power amplifiers to transmit and receive signals. By using envelope tracking chips, these systems can achieve higher levels of efficiency, reducing the amount of energy required to operate them. In turn, this could lower operational costs and reduce the heat generated by the equipment.
Furthermore, by improving energy efficiency, envelope tracking chips can allow medical imaging devices to work more reliably and consistently over time, offering better image quality and performance without the risk of overheating or power-related malfunctions.
3. Compacting Devices for Minimizing Patient Discomfort
Envelope tracking chips also help in making medical devices more compact without sacrificing power or performance. In the field of implantable devices, for instance, there is a constant push to create smaller and less invasive technology. By utilizing envelope tracking technology, medical manufacturers can reduce the size of power amplifiers and other key components in devices like hearing aids, pacemakers, or neurostimulation devices, leading to more comfortable experiences for patients.
