Case Study

Product Development for Innovative Start-Up

Services Used


An innovative tech start up in the Middle East approached us to provide them with electronic product development services. They wanted to develop a cost sensitive product which used a force sensor. 

The company have big plans to provide their vast target audience with an innovative new way to train and to help people keep track of important activities.  


The company were keen to create a product that could be safely transported and needed a safe  battery chemistry for the expected high temperatures and the predicted rough handling from users.. 

The sensor needed to work when packaged within fabric and allow for folding and rolling of the product with its associated buttons and LEDs. 

In addition, there was a tight budget for the BOM (Bill of Materials) and bulk product manufacture. 



We considered battery pack options; lithium ion was considered for its weight and energy density but this was discounted due to risks around battery damage and high temperature charging.  So, we chose a battery solution which resolved both the safety concerns and the risk of damage to the product. 

Next we considered switches and force sensors looking at a wide variety of solutions. Initially we found the desired force sensor contributed around 80% of the cost of the product. So, we set about investigating ways of achieving the same thing without the cost. As we developed the design it became clear that the force sensor didn’t require a high degree of accuracy. It just needed to be enough to recognise a touch. 

We began prototyping the sensor using various materials and PCB patterns. The solution we developed was 1/10th of the cost of the original force sensors with a cost of $0.2 vs force sensor cost of $22 – a significant saving indeed. 

With the prototype sensor produced the rest of the product was architected into several individual PCBs connected by off shelf flat flex PCBs. We evaluated the options of flexi- and rigid-flex pcbs here. At the initial launch volumes these add cost without bringing much benefit.  This can be revisited as sales volumes increase. 

The PCB designs were completed, firmware written, prototype bring up completed and tested and samples shipped for testing and feedback. 


The customer is now at the prototyping stage in the Middle East for a test run. Their device has huge market potential and can be transported safely. The electronics and software allow the product to be flexible enough for its set purpose and is suitable for the hot climate.
