The process of low power medical device development begins with the conception of a low-power medical device prototype. This enables developers to gather feedback from real users and ensure that power management solutions are effective. After a prototype is finalized, the device is tested for mass production to ensure compliance with all the regulatory standards for medical devices.
Challenges
Low power is a challenge for a variety of medical devices. While implanted devices typically operate on batteries, other devices use energy harvesting techniques to provide their power. To reduce costs and ensure long battery life, low-power devices must be highly reliable. To ensure reliability, designers should select failsafe electronic components and work with a supplier that can meet industry-specific standards.
Another challenge is finding reliable sources of materials. Manufacturers of medical devices are subject to a high level of regulation and must ensure that their suppliers meet stringent quality and reliability standards. In addition, sourcing materials can be challenging, especially in today’s supply chain disruptions. Choosing the best materials is essential for a successful design. Materials should be selected based on the device’s intended use, life span, and dimensions. Different materials may be needed for a single-use item, an implant, or a light source.
The current state of development
Low-power medical devices are becoming more commonplace. As implantable devices, they can monitor a wide range of physiological parameters. These devices can also be used for drug delivery and temperature monitoring. The demand for battery-free, wireless IMDs is growing rapidly. Wireless devices eliminate percutaneous wires and enable less intrusive implant placement. Wireless implants also allow researchers to study animals in more natural settings.
Developing a low power medical device development starts with a researcher identifying an unmet need. The researcher then develops a concept to fill this need. The next step is the creation of a proof-of-concept brief that outlines the steps required to validate the product’s viability and demonstrate financial opportunities. The brief also identifies the product class and determines how testing and certification will be conducted.
Alternative sources of power
Currently, the vast majority of medical devices rely on batteries to operate. But these batteries are not always sufficient, especially for larger, complex devices. This is a major barrier to innovation. Despite the need for battery power, medical device manufacturers are still working to minimize their power consumption while maintaining the same level of functionality. Some of the technologies that have recently been developed include ultra-low-power microchips and energy harvesting.
