Cala Trio is a simple wearable device similar to a watch. It is the world’s first wrist-worn non-invasive therapy that reduces hand tremor, delivering a personalized therapy that targets the source of the tremor. It is an FDA-approved wearable device provided in the form of a consumer wearable, along with an easy to use connected charging station.
Cala Trio was highly focused on product design and engaged Kaizen Dynamic to assist in Cala Trio’s development of an optimized design for mass production.
This is a stand-alone device that is not app-driven and does not require a smartphone. The Cala Trio device and charging station utilize BLE and custom LTE and NFC antennas to ensure seamless system communication and data management without requiring any work from the user to connect or input data.
The nature of essential tremor means that it is difficult for users to operate small buttons and carry out intricate actions that are usually associated with most wearables. KD provided detailed engineering and development on a number of product features including the following:
All required many design and prototype iterations for user testing before finalizing a design that satisfies all challenges creating an intuitive solution.
Embedded in the microfiber wristband is a flexible PCB with overmolded conductive silicon electrodes. Comfort and ease of use while delivering reliable therapy are critical to the user experience.
KD worked closely with the Cala Health team from the early prototyping stages through to product design, development and implementation. KD helped Cala Health bring their product in production and available for purchase. KD is very proud to have been given the opportunity to partner with Cala Health in delivering such an impactful product to market.
