Flexible Ultrasound Patch 08
ULTRASOUND

Flexible Ultrasound Patch

A skin-conforming ultrasound array for long-term non-invasive monitoring of vessels, muscle and flow — turning ultrasound from an examination into a monitor.

Acoustic Pickups 09
PICKUP

Acoustic Pickups

Converts mechanical vibration of an instrument soundboard, cavity or pipe wall directly into audio, bypassing airborne noise entirely.

Flexible Actuators 10
ACTUATOR

Flexible Actuators

Running the piezoelectric effect in reverse: applying voltage deforms the film, driving haptic feedback, micro-pumps and compliant mechanisms.
