How To Mitigate The Challenges Of Wearable PCB Designs
Posted: Aug 08, 2019
The technology of today’s world delves into the medical, fitness, and mass consumer product industries. It is the age of wearable technology, and industrialists want to introduce innovation in research, health-monitoring, and fashion. Then again, there are many technical challenges that engineers have to face. The products are small and intricate. Naturally, the price to pay for them is high. Here are the common problems faced by companies attempting to create wearable PCBs. You will also receive some support regarding combating those issues.
Shape and size: The gadgets of today have to be tiny but full of features. It can make an engineer experience massive headaches. It doesn’t matter whether they are using a pre-built flex circuit board or creating it themselves. After the matter concerning size, designers have to worry about the shape. The best way to handle the problem is by utilizing the board space optimally.
The material: It is already difficult to create small and intricate boards. You can solve that issue by contacting a company specializes in the manufacturing of a flex circuit board. Once you take care of that matter, you have to work with unusual materials like plastic, fabric, Flexi-rigid substances, and mesh. Of course, you have to resort to the support of reliable flex circuit manufacturing companies.
The power: Most wearable gadgets rely on batteries or energy harvesting machines. It means that the devices have to be strict about power consumption. You can take care of the problem by planning for power. You should approach the issue with an energy budget. Break everything into individual tasks or power consumption allowances for each circuit block.
The connectivity: Connectivity is, obviously, at the core of most wearable products. Wi-Fi, Bluetooth, or other protocols are parts of most wearable gadgets. You should feel thankful towards the IoT. They are available everywhere, and so, you will find small connectivity devices. They are tiny enough to fit into the designs appropriately. They cover almost all connectivity-related protocols.
The antenna design: Things can be a bit too tricky for you when you have to place antennas in the machines. Transmitting and receiving signals near the human body can be problematic. Of course, there is a way to tackle this issue with wearable gadgets. You have to ensure that the electromagnetic fields concentrate well away from the body of the wearer.
The humidity: Apart from creating problems regarding signal transmission, the human body emits moisture. As an engineer, you should be aware that moisture can damage PCBs. So, you should consider sealing the PCB hermetically. It will prevent the moisture from penetrating the product at all. If you can’t apply a hermetic coating, consider conformal coating it.
The future is bright
There is no secret behind the fact that consumers are seeking more wearable products nowadays. You also know about the issues about creating such devices. However, problems always come with solutions. So, you shouldn’t have much trouble in producing wearable gizmos. If anyone says that wearable gadgets are at the end of their possibilities, then they aren’t trying hard enough. The future of wearable devices is shiny, indeed.
