Since any BLE reader can be configured to read a Battery-Assisted Pixel, and no additional infrastructure is required, the entry price and complexity of tagging things will be dramatically reduced. The BAP is a great springboard to leveraging Wiliot Pixels. We expect it to significantly accelerate the adoption and development of Works with Wiliot solutions. In the long-term battery-free or passive tags will sell in much higher volumes, addressing many more use cases and adding connectivity and intelligence to much lower cost items.
Some of the advantages of a Battery-Free Pixel (BFP) over a Battery-Assisted Pixel:
Cost - Battery-free Pixels (BFP) will be an order of magnitude lower in cost. We expect Battery-free IoT Pixels to cost less than 10c by end of next year.
Size - They are significantly smaller in size (postage stamp size versus business card size).
Longer Lifetime – Battery-Assisted Pixels (BAP) will last up to 3-4 years – a Battery-free Pixel will last as long as the structure of the tag will last, this could be over a decade.
Robust and embeddable – BFP’s are a simpler design, they can survive being frozen at cryogenic temperatures, operate at colder temperatures, can be embedded in other materials such as injection molds, can be more flexible and washable when attached to garments.
Speed – BFPs can broadcast faster than a BAP when close to an energy source. This can be useful when tracking faster moving assets.
Are there any other differences between the BAP and the BFP?
The software running on the BAP is different to that running on our battery free product, even though the chip is the same. The flexibility to run different programs on these two tiny computers allows us to capitalize on and optimize the operation of the two different systems and has allowed us to deliver the products to market faster than if the tags had a more basic hardcoded design.
