What is Flexible Memory?
Flexible memory refers to data storage devices that are built on flexible, bendable, and lightweight substrates, enabling them to conform to non-planar surfaces. These devices are crucial for wearable electronics and other flexible systems, offering both mechanical flexibility and reliable performance.
Substrates Used to Fabricate Flexible Memory
- Polyimide (PI): High thermal stability and flexibility.
- Polyethylene Terephthalate (PET): A low-cost, lightweight option.
- Polyethylene Naphthalate (PEN): Offers superior mechanical properties over PET.
- Polydimethylsiloxane (PDMS): Stretchable and transparent for soft electronics.
- Ultra-Thin Glass: Combines flexibility with excellent barrier properties.
- Metal Foils: Durable substrates like aluminum or stainless steel.
- Paper: Low-cost and eco-friendly option for specific applications.
Applications of Flexible Memory
- Wearable electronics like fitness trackers and medical sensors.
- Flexible displays for foldable phones and tablets.
- Internet of Things (IoT) devices.
- Energy harvesting systems integrated with memory.
- Biomedical devices for health monitoring.
