CipherBionics — Functional bionic hands. Under $2,000.

The problem

The tech exists. Access doesn't.

Myoelectric prosthetics are a solved engineering problem in wealthy markets — and entirely out of reach almost everywhere else.

01

1.5B

Massive unmet need

People live with disability globally. Upper-limb prosthetic access across MENA is near-zero for most amputees.

02

$10k+

Price barrier

The lowest-cost functional myoelectric hands start around $10,000. For most people, the technology exists — affordability doesn't.

03

Built for
insurance

System mismatch

Existing products target insurance markets and high-cost healthcare — not local manufacture, serviceability, or NGO distribution.

Our solution

Meet CipherGrip.

An EMG-controlled bionic hand built to close the affordability gap — now real hardware, not a roadmap.

An EMG-controlled prosthetic hand engineered for emerging markets — under $2,000, intent-driven, serviceable, and manufacturable locally.

Robust EMG decoding

A proven EMG pipeline detects intent from residual forearm muscles — fast open/close control with low false activations.

Designed for service

Modular fingers, replaceable actuators, and field-repairable electronics — with parts sourced from regional suppliers.

Local manufacturability

A 3D-printable design with locally sourceable components — repairable by a technician with basic tools, anywhere.

Introducing

CipherGrip — the hand, realized.

Not a concept. Not a render. A working five-finger EMG bionic hand, built and running on the bench.

● CipherGrip — live demo

On the bench

CipherGrip takes the EMG decoding proven in HexDigit and scales it into a full articulated hand — reading intent straight from the forearm and translating it into real grip. Everything the field needs, at a price the field can actually reach.

True EMG control

Reads muscle intent from the residual forearm for natural open and close.

Five articulated fingers

Multiple functional grips for the tasks of everyday life.

3D-printed & serviceable

Field-repairable with locally sourced parts and basic tools.

Under $2,000

A fraction of the cost of comparable myoelectric hands.

Product lineage

From a third thumb to a full hand.

CipherGrip isn't a render. It stands on hardware that's already in the world — built, documented, and shipped.

Proof of concept · Live

HexDigit

The world's first openly available EMG-controlled wearable third thumb. Live on GitHub with a reproducible signal stack, and backed by Upside Down Labs — a working proof that the control pipeline holds up in the real world.

"I taught myself EMG. I printed in TPU for the first time. I built it, documented it, and gave it to the world for free. That's what happens when I put my mind to something. CipherGrip is next."
