# TinyProbe v0.1.0
### A Wearable 32-Channel Multi-Modal Wireless Ultrasound Probe

## Introduction

This repository contains ongoing work on **TinyProbe**, an advanced wearable ultrasound platform developed at the [Integrated Systems Laboratory (IIS)](https://iis.ee.ethz.ch/) of ETH Zurich.

The system design is described in detail in our publications in the [IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control (TUFFC)](https://ieeexplore.ieee.org/document/10750870) and in the [Proceedings of the IEEE International Ultrasonics Symposium (IUS 2025)](https://2025.ieee-ius.org/).

## Specifications

TinyProbe is a compact research platform for low-power ultrasound sensing, featuring the following specifications:

### Transmit
- **64 V peak-to-peak** bipolar excitations  
- **32 pattern profiles** (fully programmable)  
- **16 delay profiles** (fully programmable)

### Receive
- **21, 18, or 15 dB** low-noise amplifier (programmable)  
- **21, 24, or 27 dB** programmable gain amplifier (PGA)  
- **Up to 36 dB TGC** (fully programmable)  
- **32 channels** (simultaneously sampled at up to **30 MSps, 10 bit**)

### Connectivity
- Wireless link I (Wi-Fi 4, **21.6 Mbps**)  
- or Wireless link II (Wi-Fi 6, **35.7 Mbps**)

### Operating Modes
1. **A-mode**, **B-mode**, **M-mode** with 32 channels (**33 FPS with Wi-Fi 4, 55 FPS with Wi-Fi 6**)  
2. **Doppler mode** with 2 channels (**1400 FPS**)  
3. **Raw RF data streaming** (**55 FPS**, 32 channels, 2000 samples per channel, 10 bit per sample)

### Power Consumption
With Wi-Fi 4 shield:  
- **970 mW** for operating modes 1 and 3, **1400 mW** for operating mode 2  
- **100 mW** in power-save mode

## Repository Structure

This repository has the following folders:

- `wifi_6_board`: source files for the Wi-Fi 6 board, namely:  
  - firmware for the SiWG917 MCU, located in `fw/`  
  - CAD design files for the Wi-Fi 6 PCB shield, located in `hw/`  
- `acquisition_board`: source files for the acquisition board (Work in Progress)  
- `hv_tx_board`: source files for the high-voltage PCB (Work in Progress)  
- `host_pc`: Python code for the TinyProbe Python interface  
- `docs`: project documentation (Work in Progress)

## Documentation

Additional documentation (e.g., how to reproduce results, how to use the probe) will be added in later releases.
