SentinelWear - Passive Sexual Assault Detection and Deterrence

She drank too fast because the cute guy from the music theory class finally talked to her. She remembers kissing him. She remembers sitting on the couch. Everything after that is black. Her friends found her in a room upstairs, half-dressed and mumbling. She blamed herself for weeks — for drinking too much, for not saying no clearly enough, for not remembering. She never reported it. She didn’t think anyone would believe her. With SentinelWear on her wrist and in her pocket, the phone recorded a clear biometric shift: HRV collapse, audio of her slurring, then silence. The device captured rhythmic motion for eight minutes while her vitals remained flat. Later, when she tapped to review her timeline, it was all there — not just a suspicion, but a sealed, timestamped record. She didn’t have to prove anything from memory. The data spoke for her.

She left the bar early, tired, and ordered a rideshare. The driver was chatty, then started asking if she lived alone. He didn’t take the freeway. She doesn’t remember falling asleep — just waking up in a parking lot with her skirt twisted and a dull ache. There were no bruises. No rape kit. Her friends weren’t sure what to say. With SentinelWear, her phone quietly noticed the HR dip and lack of movement. When the car stopped for ten minutes in an unlit lot, her device sealed a log: sudden orientation shifts, minimal reactivity, muffled audio. It wasn’t conclusive proof of rape — but it showed she didn’t consent. And it showed where, and when. That changed the conversation. She wasn’t imagining it.

She worked in finance. A big client from out of town asked her to dinner. She’d been coached to be friendly, keep the account. He ordered wine, touched her arm too long. She laughed it off. Later, she woke up naked in the hotel room shower. He was gone. She found a $100 bill on the nightstand. She never told anyone. She still doesn’t know what happened. With SentinelWear, her watch tracked her HR drop 40 minutes after her second glass of wine. Her phone recorded her voice slowing, then stopping. Ten minutes of unsteady motion followed. The phone never unlocked again that night. She didn’t even look at the logs right away. But knowing they were there gave her the strength to talk to someone. To name it. To not gaslight herself.

She didn’t want to go home after her shift, so she went to a co-worker’s place to hang out. They smoked. Watched a show. He kissed her. She wasn’t into it, but didn’t say much. When he got on top of her, she froze. Later, she told a friend it “wasn’t really rape,” just “a bad vibe.” She hated herself for not pushing him off. With SentinelWear, her phone showed a period of no motion, no vocalization, followed by thrusting-like movement while her HRV was nearly flat. It matched sedation or freeze. It wasn’t for a court. She didn’t file a report. But when she read the data, something clicked. She stopped blaming herself. She started calling it what it was.

She had nowhere to stay after a breakup, so she crashed at a friend’s place. They’d known each other for years. He offered the couch. She woke up at 4 a.m. to find him between her legs. When she confronted him, he said, “You didn’t say no.” She moved out. She didn’t press charges. She couldn’t prove anything. With SentinelWear, her body recorded the moment: HR spike, then flattening, no movement for several minutes, while the phone captured intermittent thrusting motion. She didn’t need to explain her freeze. The data made it clear. She handed it to a lawyer, not because she wanted jail — just protection. An order. A record. She got it.

She went to the bathroom, dizzy from the last round. A guy she didn’t know followed her in. She remembers the stall door slamming. Then nothing. The next morning she was bleeding and sore, her underwear missing. She told the bartender. He shrugged. With SentinelWear, the device logged a sudden movement burst, then six minutes of rhythmic pelvic motion while her HRV was suppressed and audio showed no vocalization. Combined with the GPS pin at that exact time and place, she had what police call “corroborative forensic evidence.” For the first time, they actually listened.

She was too tired to argue with her friends, so she ordered the Uber like they told her. The driver seemed polite, asked if she was okay. She doesn’t remember passing out. She woke up in her own bed, confused. Her underwear was gone. Her phone was on the floor. There was no memory of the drop-off. No bruises. She filed a complaint with Uber, but they said the ride ended normally. With SentinelWear enabled, her device recorded a sudden HRV suppression at 12:44 a.m., shortly after she got in the car. Her HR stayed flat despite prolonged motion and GPS location shifts inconsistent with the route home. Audio showed muffled shuffling and zipper sounds during a five-minute stop near a dark parking lot. She had no memory, but the data was airtight. When she showed the report to a lawyer, she wasn’t just another blackout case — she was a credible complainant, backed by sealed biometric truth.
