Sensors used to monitor extreme environments need to provide reliable measurements despite high temperatures and harsh conditions. Now, researchers have developed a piezoelectric sensor that works at ...

Working within the Holst Centre program on Micropower Generation and Storage, researchers have developed a small piezoelectric device capable of harvesting 85 microwatts of electricity from vibrations ...

MIT researchers have created a new underwater sensor and communication system that doesn’t require batteries, and barely uses any power at all. This could help set up an underwater Internet of Things, ...

Piezoelectric power, or electricity produced in response to applied mechanical stress, keeps popping up on our radar. Recently, we looked at a French city’s plan to implant piezoelectric microsensors ...

Researchers have developed a battery-free underwater communication system that uses near-zero power to transmit sensor data. The system could be used to monitor sea temperatures to study climate ...

Ultrasonic sensor transducers work well in medical applications such as patient monitoring, flow measurement and air bubble detection used in infusion systems, pharmaceutic devices or spirometry.

Centimeter-scale robots have unique advances such as small size, light weight, and flexible motions, which exhibit great application potential in many ...
