Science Daily January 17, 2023 For detecting a potential collision at night to alert the driver or, maneuvering system of an autonomous vehicle, current technologies utilize resource draining and expensive solutions such as LiDAR or image sensors coupled with extensive software running sophisticated algorithms. In contrast, insects perform the same task of collision detection with frugal neural resources. Researchers at Pennsylvania State University have shown that insect-inspired collision detection algorithms, when implemented in conjunction with in-sensor processing and enabled by innovative optoelectronic integrated circuits based on atomically thin and photosensitive memtransistor technology, can greatly simplify collision detection at night. The […]

Memristive spintronic neurons: Combining two cognitive computing nano-elements into one
Nanowerk December 6, 2021 For ultrafast non-conventional computing synchronization of large spin Hall nano-oscillator arrays tuning its individual oscillators and providing built-in memory units remain substantial challenges. An international team of researchers (Sweden, India, Japan) has demonstrated the integration of a memristor into another, a spintronic oscillator. Arrays of the memristor-controlled oscillators combine the non-volatile local storage of the memristor function with the microwave frequency computation of the nano-oscillator networks and can closely imitate the non-linear oscillatory neural networks of the human brain. Using the memristor-controlled spintronic oscillator arrays, they could tune the synaptic interactions between adjacent neurons and program […]
Towards next-gen computers: Mimicking brain functions with graphene-diamond junctions
Science Daily August 4, 2021 Researchers in Japan designed graphene-diamond junctions that can mimic the characteristics of biological synapses and key memory functions, opening the doors for next-generation image sensing memory devices. They demonstrated optoelectronically controlled synaptic functions using junctions between vertically aligned graphene (VG) and diamond. The fabricated junctions mimic biological synaptic functions when stimulated with optical pulses and exhibit other basic brain functions such as the transition from short-term memory (STM) to long-term memory (LTM). The VG-diamond arrays underwent redox reactions induced by fluorescent light and blue LEDs under a bias voltage. The researchers attributed this to the […]
