Despite recent advances in technology for upper-limb prostheses, artificial arms and hands are still unable to provide users with sensory feedback, such as the “feel” of things being touched or awareness of limb position and movement. Without this feedback, even the most advanced prosthetic limbs remain numb to users, a factor that impairs the limbs’ effectiveness and their wearers’ willingness to use them. In a step toward overcoming these challenges, DARPA has awarded prime contracts for Phase 1 of its Hand Proprioception and Touch Interfaces (HAPTIX) program.
DARPA has selected seven teams of researchers to begin work on the Agency’s Electrical Prescriptions (ElectRx) program, which has as its goal the development of a closed-loop system that treats diseases by modulating the activity of peripheral nerves. The teams will initially pursue a diverse array of research and technological breakthroughs in support of the program’s technical goals. Ultimately, the program envisions a complete system that can be tested in human clinical trials aimed at conditions such as chronic pain, inflammatory disease, post-traumatic stress and other illnesses that may not be responsive to traditional treatments.
Pressure—the physical quantity of an experience of touch—is a fundamental dimension of human perception, conveying to the brain not just that the skin is in contact with something, but also how intense the contact is. That awareness is what enables people to, for instance, gently but securely handle an egg without squeezing so hard that the shell cracks.
Blast injuries, burns, and other wounds experienced by warfighters often catastrophically damage their bones, skin, and nerves, resulting in months to years of recovery for the most severe injuries and often returning imperfect results. This long and limited healing process means prolonged pain and hardship for the patient, and a drop in readiness for the military. However, DARPA believes that recent advances in biosensors, actuators, and artificial intelligence could be extended and integrated to dramatically improve tissue regeneration. To achieve this, the new Bioelectronics for Tissue Regeneration (BETR) program asks researchers to develop bioelectronics that closely track the progress of the wound and then stimulate healing processes in real time to optimize tissue repair and regeneration.
The Bioelectronics for Tissue Regeneration (BETR) program will develop technology aimed at speeding warfighter recovery, and thus resilience, by directly intervening in wound healing. To do this, researchers will build an adaptive system that uses actuators to biochemically or biophysically stimulate tissue, sensors to track the body’s complex response to that stimulation, and adaptive learning algorithms to integrate sensor data and dictate intervention to the actuators.
