Example brief · not client workWe wrote this brief ourselves; it is not client work. The 3D model, drawings and inspection results are in production and will replace the placeholders below.
The request, as a client would send it
Our lab develops a stretchable conductive ink. We want a glove that shows it working: five traces printed on TPU film, one along each finger, change resistance as the fingers bend, and a small screen on the wrist shows each finger's bend live. We will print and laminate the traces ourselves. We need everything else: the wrist module and its strap, a way to connect the soft traces to the rigid board that survives people trying the glove on all day, and anchors at the fingertips. Wrist module: an Arduino Nano 33 BLE (45 x 18 mm), a 500 mAh LiPo (about 35 x 30 x 5 mm) with a charger board, and a 0.96 inch OLED (27 x 27 mm module). We have all three. Each trace goes to an analog input through a divider. Please send the parts, instructions we can follow in the lab, and the code. It is for a conference booth, so it will be put on and taken off many times.

Highlighted numbers came with the request; they are the values we would design to.
What we considered
| No. | Consideration | How it is checked |
|---|---|---|
| 01 | Soft traces meet a rigid board A clamp at the wrist presses each trace onto a contact pad, with strain relief so pulling the glove on does not load the joint. | Clamp fits the trace width and film thickness; strain-relief length listed. |
| 02 | The wrist module fits the parts the lab has Board, battery, charger and screen stack inside a module sized for a wrist, with the USB port and switch reachable. | Parts placed with clearance; port and switch access zones clear. |
| 03 | Many hands, all day The strap, the fingertip anchors and the clamp are designed to be put on and taken off again and again. | Anchor and strap geometry listed; wear is not tested. |
| 04 | Code and instructions the lab can run The code reads five dividers, calibrates each finger at start, and draws five bars on the OLED. | Pin map matches the wiring diagram; the code builds for the Nano 33 BLE. |
The question we would ask you
Should the glove also send the readings to a laptop?
Bluetooth to a laptop adds a small app on the lab's side and changes the code; the screen on the wrist alone keeps the demo simple.
What we do not claim
- Electrical performance of the lab's conductor
- Accuracy of the bend readings
- Wear or wash resistance

Model, drawings, parts list and inspection report
The 3D model, dimensioned drawings, parts list, and the first-try and final inspection results will appear here after the first build. First-try failures stay visible.
