How Microprocessor Technology Works
Microprocessor controlled feet respond to constant feedback from sensors to the onboard computer, which changes the resistance to plantarflexion (downward motion) and dorsiflexion (upward motion) of the foot based on walking speed, incline, decline and type of terrain. Adjustments are made in real time. Some designs communicate with smartphones via Bluetooth. Microprocessor controlled feet require nightly recharging, similar to a cell phone.
There are also integrated microprocessor knee/feet/ankle systems available, such as the
Linx system from Blatchford.
The élan is a microprocessor-controlled hydraulic foot from Blatchford that uses patented technology to provide a simulated plantarflexion assist during fast walking on level ground and a brake effect when walking down an incline. That makes it easier to negotiate uneven terrain, slopes and ramps with less effort, increased stability and greater confidence.

Additional Benefits of the élan:
Improved ground clearance in swing phase
Enhanced security and stability
Even loading between limbs
Incorporated battery, self-contained device
Rechargeable battery that lasts a minimum of 24 hours
Clean / sleek look
Ability to be cosmetically covered
The élan is recommended for moderately active amputees with the ability or potential for ambulation with variable cadence and who may benefit from enhanced security and functionality and increased confidence on uneven surfaces.

Kinnex Microprocessor Ankle/Foot System
Kinnex, from Freedom Innovations, is the first-ever waterproof microprocessor-controlled foot. This allows users to fully immerse the foot in water, making it possible to enjoy many activities without changing your foot, such as paddle boarding or visiting a waterpark with your children. Using embedded sensors and built-in Bluetooth connectivity, the Kinnex can sync to a mobile app on users' smart phones, allowing for real-time feedback and adjustments including up to two inches of heel height. The app can store settings for up to 100 shoes, so users can wear more types of shoes with different heel heights.
