Hardware Design

The miroCard is a light-powered smartcard built with privacy and security in mind. It features advanced sensing and communication capabilities, enabling innovative applications.

This batteryless ambient sensor can broadcast BLE advertisements with sensor data. It can also transmit historical sensor data stored in non-volatile memory with relative timestamps.

This batteryless system uses a privacy-enabling thermal camera, and can run machine learning algorithms to detect the number of people in a room.

This mixed-signal system facilitates energy measurements in batteryless deployments. It automatic range switching enables accurate current measurements from nA to mA.

This batteryless system features a vision sensor, a microcontroller and a BLE radio, and can execute computer vision algorithms.

This batteryless system, when worn properly, can estimate the user’s walking speed using an optical-flow algorithm.

This sensing device uses a multi-core RISCV platform to perform energy-efficient processing and has long-range communication capabilities.

This measurement platform can be deployed to gather long-term data about photovoltaic harvesting in indoor environments. It can also be configured to gather ambient data to correlate it with energy availability.

The Energy Management Unit (EMU) allows reliable task-based execution, even under variable energy-harvesting conditions. The EMU is a fundamental element in highly optimized batteryless sensors.
